Description

The C2304 is a flexible high intercept and high gain down conversion GaAs MMIC packaged in a compact 14

pin SOIC package. Each sub-circuit is brought out on separate pins to allow for custom filtering on the IF/RF

mixer interstage or custom matching for specific bands. Broadband parallel feedback networks are used on the

gain and LO driver stages and the mixer is a singly balanced, two diode type mixer. The FET source of the IF

amplifier stage (IF BIAS) is accessible for AC bypassing which allows for current reduction with DC source

degeneration. The gain and DC current is broken up as follows: RF AMP gain = 14dB, current = 22 mA; LO

AMP gain = 11dB, current = 28ma; IF AMP gain = 18dB, current = 60 mA, MIXER conversion loss = -6dB.

Simple external matching circuits can be implemented for all ports to achieve VSWR’s <2:1 over moderate

bandwidths of less than 400MHz.
