2-18 GHz Down Converter for EW and ECM Applications

SUNNYVALE, CA--Endwave Defense Systems, a manufacturer of RF subsystems and components for defense and homeland security applications, has announced the release of a new down converter module that operates over a broad frequency range of 2-18 GHz, making it ideally suited for Electronic Warfare (EW) and Electronic Counter Measures (ECM). The module down-converts the broadband RF input signal to a UHF frequency on the IF output. A high isolation buffer amplifier at the LO input, along with tight filtering on RF, LO, and IF ports, helps to minimize spurious signals at all inputs and outputs. A broadband limiter is incorporated on the RF front-end for receiver protection, and temperature compensation is used to provide a stable RF-IF gain response over an extended military operating temperature range. Typical performance for the down converter includes a conversion gain of 20 dB, a noise figure (NF) of 5 dB, an input one dB compression point (P1dB) of -15 dBm, and an input 3rd order intercept (TOI) of -5 dBm. Special attention has been paid to the mechanical design of the microwave subsystem to provide over 50 dB of LO rejection to the RF input port.
