We designed, bult and tested 2 new RCT0056 RF Receiver Simulators. These simulators match the performance of an RF system front end (noise figure, gain, Pin1dB, slope), and when connected to the back end of the system, the full system can be tested without the need for actual front end hardware. 12 Frequency bands were were provided, from VLF up to mmW frequencies. Adjustable attenuators with front panel controls were added to allow gain adjustment during testing.
We designed and built an RF Receiver Sumiulator RCT0053, designed to simulate the front end characteristics of an EW system, from the antennas to the downstream rack equipment. We used our customer designed RCT0050 WB amplifiers in many of the 6 microwave channels.
A LB RF Receiver Simulator was designed to simulate the RF front end of a submarine periscope subsystem. The noise figure, gains, and dynamic ranges were designed to simulate the actual subsystem. The amplifiers were custom designed and equalized by R. A. Wood Associates to cover a wide bandwidth from ~DC to 3 GHz. A variable attenuator allowed the output noise floor to be adjusted in 1 dB steps.
We've delivered our fourth RF Receiver Simulator, and our 6th of a family of Receiver Simulator products. The simulators are designed to represent the RF front end (noise figure, gain compression point, and intercept point) of a complex EW system, to allow testing, verification and validation of the EW system back end, without requiring the expensive front end components.
If you have a need for one of these types of products, please contact us.
We've delivered another RF Receiver simulator to one of our customers. This unit simulates the RF front end characterisitcs (noise figure, gain, dynamic range) of an EW system, so the customer can connect it to their back end system and validate full system end to end performance (system sensitivity, etc), without requiring the expensive front end components. Frequency coverage goes from 10 MHz to 40 GHz on this unit.

Hello Everybody
We just delivered our latest product: a multi-channel RF/Microwave Receiver Simulator. This device simulates the RF front end of an ESM (Electronic Support Measures) system. The simulator matched the noise figure, gain and dynamic range of the RF front end. The simulator contained 9 channels of RF bands covering from 10 MHz all the way up to 40 GHz.
Some pictures of the RF Receiver Simulator are shown below. The RF Receiver Simulator is a 3U rack-mounted assembly mounted in a protective roll-away cart for ease of transportability.
We just delivered an EW Receiver Simulator to one of our customers. The simulator provided the simulated RF and microwave front end performance of an EW (Early Warning) Receiver subsystem. Our simulator allows the EW Receiver/Processor to be evaluated without requiring the actual front end system. The simulator was designed to match the system front end noise figure, gain, and dynamic range. This also represents a new modular and mechanical design for us.
A block diagram of one channel of the EW Receiver Simulator is shown below:
Some pictures of the EW Receiver Simulator are shown below. The box is built to be used as bench-top equipment or as a 3U rack-mount installation. This is the first design of our standard rack-mount chassis, capable of supporting up to 16 plug-in modules (1 inch standard width). Cooling air is pulled from front to back, and the modules are thermally clamped (with Calmark Clamps) to the top and bottom of the chassis.
We delivered a wideband RF/microwave Receiver Simulator to one of our clients on March 1. The simulator was designed to simulate the front end of an RF/Microwave system. Frequency coverage went from HF to SHF Ka Band. The simulator was required to have very low noise figures and very high intercept points/compression points. The unit was delivered in 6 months after order. More information is available at this link location.
