Abstract
A receiver is operable at microwave frequencies and includes a substrate and waveguide-to-microstrip transition formed on the substrate for receiving microwave radio frequency (RF) signals. Surface mounted receiver components are interconnected with microstrip formed on the substrate and receive the RF signals from the waveguide-to-microstrip transition and convert the signal to an intermediate frequency (IF) for further processing. The surface mounted receiver components include a mixer circuit that receives a local oscillator (LO) signal and RF signal to produce the IF signal. A diplexer circuit and a temperature compensated attenuator circuit received the IF signal from the mixer and attenuates the IF signal to provide high signal linearity and high order modulation.
