Description
The C2306 is a flexible, high intercept, frequency conversion GaAs MMIC packaged in a 14 pin SOIC
package. The MMIC is usable as an upconverter or downconverter mixer. Each subcircuit 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 mixer. The FET source of the IF amplifier stage (IF BIAS) is accessible for AC bypassing
which allows for current reduction with self bias circuitry. The gain and DC current is broken up as follows:
LO AMP gain = 11dB; current = 27 mA, IF AMP gain = 17dB, current = 60mA, Mixer conversion loss = -
6dB. Simple external matching circuits can be implemented for all ports to achieve VSWR鈥檚 < 2:1 over
moderate bandwidths of less than 400MHz.
