RF-Lambda RF Components up to 120 GHz: Switches, Filters and Waveguides

RF-Lambda Expands Its RF and Microwave Component Portfolio up to 120 GHz

Modern RF and microwave systems face increasing requirements for signal control, routing and integration. Automated test environments, radar systems, satellite communications and next-generation wireless infrastructures rely on RF components capable of supporting precise and repeatable signal handling.

RF-Lambda continues to expand its portfolio of active, passive and waveguide components, covering applications across a frequency range from DC to 120 GHz.

The expanded portfolio addresses five key product areas: RF switches, attenuators and phase shifters, filters and multiplexers, waveguide components, and isolators, circulators and power dividers.

1. RF Switches – Fast and Flexible Signal Routing

RF switches are essential components in automated measurement environments where RF signals must be routed between multiple instruments, devices under test or signal paths.

RF-Lambda has expanded its range of PIN diode, GaAs and GaN switches, offering configurations up to SP160T, with fast switching capabilities and high isolation depending on the selected model.

A key development is the availability of USB- and Ethernet-controlled RF switches, enabling direct software-based control and reducing the need for dedicated external controllers in certain test configurations.

Key features:

• RF switch technologies including PIN diode, GaAs and GaN.
• Switch configurations up to SP160T.
• Fast switching and high isolation, depending on the model.
• USB and Ethernet interfaces for software-based control.
• Integration into automated RF testing environments.

Typical applications: automated RF test benches, multi-channel measurement systems, laboratory signal routing, radar testing and communication system validation.

Important selection parameters include operating frequency, insertion loss, isolation, switching time, RF power handling and the required port configuration.

2. Digital Attenuators and Phase Shifters – Precise RF Signal Control

Accurate signal level adjustment is a fundamental requirement in RF testing and system development. RF attenuators provide controlled signal reduction and help establish repeatable measurement conditions.

RF-Lambda offers PIN diode switched-bit digital attenuators with binary 4- to 6-bit configurations. The portfolio includes versions providing 0.5 dB attenuation resolution and models offering a total attenuation range of up to 63 dB. These specifications depend on the individual model.

The product range also includes manual rotary attenuators, designed for direct signal level adjustment in laboratory and test configurations.

RF phase shifters are also part of the portfolio, providing control over signal phase for applications requiring defined phase relationships.

Key features:

• Digital attenuators with 4- to 6-bit architectures.
• Models with 0.5 dB attenuation resolution.
• Versions offering up to 63 dB total attenuation.
• PIN diode switched-bit technology.
• Manual rotary attenuators for laboratory adjustments.
• Phase shifters for RF phase control.

Typical applications: RF measurement systems, radar development, 5G/6G infrastructure, signal level adjustment and transmission path testing.

Selection should consider frequency coverage, attenuation range, step resolution, insertion loss, RF power handling and the available control interface.

3. RF Filters, Duplexers and Multiplexers – Selective Frequency Management

Increasing spectral density creates additional challenges for RF receivers and communication systems. Filters and multiplexers are used to select desired frequency bands, suppress unwanted signals and separate multiple signal paths.

RF-Lambda is expanding its portfolio of high-selectivity RF filters, duplexers and multiplexers for demanding applications, particularly in aerospace and defense environments.

These components can play an important role in reducing unwanted signals at sensitive receiver inputs and managing frequency separation within complex RF architectures.

Key functions:

• Selective transmission of defined frequency bands.
• Suppression of unwanted spectral components.
• Separation of different frequency bands and signal paths.
• Support for frequency planning in complex RF systems.
• Reduction of unwanted signals reaching sensitive receivers.

Typical applications: radar systems, satellite communications, defense RF systems and frequency-selective signal distribution.

Key selection criteria include passband characteristics, stopband rejection, insertion loss, return loss, selectivity and RF power handling.

4. Waveguide Components – Signal Transmission at Microwave and Millimeter-Wave Frequencies

Waveguides are widely used in microwave and millimeter-wave systems where controlled electromagnetic signal transmission is required. They are particularly relevant in radar, satellite and high-frequency measurement applications.

RF-Lambda has expanded its range of waveguide components, including manual waveguide attenuators supporting standard waveguide sizes from WR90 to WR8.

The portfolio also includes flexible waveguides, designed to accommodate mechanical constraints and help compensate for stresses between interconnected RF assemblies.

Key features:

• Manual waveguide attenuators.
• Configurations covering standard sizes from WR90 to WR8.
• Flexible waveguides for mechanical adaptation.
• Components for demanding microwave and millimeter-wave applications.

Typical applications: satellite feed systems, radar installations, microwave measurement laboratories and RF assemblies requiring mechanical flexibility.

Selection parameters include waveguide size, operating frequency, flange configuration, insertion loss, RF power handling and mechanical integration requirements.

5. RF Isolators, Circulators and Power Dividers – Signal Protection and Distribution

Reflected RF signals can affect the operating conditions of amplifiers and other sensitive components. Isolators and circulators are used to manage RF power flow and reduce unwanted interactions between different sections of an RF system.

RF-Lambda offers a broad selection of coaxial and drop-in isolators, together with circulators for different integration requirements.

The portfolio also includes RF power dividers, designed to distribute an input signal across multiple signal paths.

Key functions:

• Isolators to reduce unwanted effects caused by reflected RF power.
• Circulators for directional signal routing between multiple ports.
• Coaxial and drop-in configurations for different system architectures.
• Power dividers for distributing RF signals across multiple outputs.
• Integration into RF amplifier, measurement and communication systems.

Typical applications: RF transmitter protection, radar systems, communication equipment, multi-channel signal distribution and automated RF test environments.

Important technical parameters include operating frequency, isolation, insertion loss, impedance matching, power handling and mechanical configuration.

RF-Lambda Components for Radar, SatCom and Automated RF Testing

The expansion of the RF-Lambda portfolio addresses several requirements of modern RF systems: precise signal control, automated routing, frequency-selective signal processing and reliable integration at high frequencies.

The combination of digitally controlled switches, attenuators and passive RF components is particularly relevant when designing complex RF measurement and communication architectures.

RF-Lambda also addresses demanding aerospace and defense applications. The company states that it holds AS9100 certification and references MIL-STD-883 requirements. Applicable qualification and testing requirements should be confirmed for each specific product.
