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's < 2:1 over moderate bandwidths of less than 400MHz.

At 3dBm drive, the f unmatched port is at Z = 5 -15j ohms at 2.278 GHz. Also of note is that this impedance varies somewhat with the LO drive level. Therefore a narrow band high Q network is not recommended due to inherent manufacturing variation in LO drive available. The simple network below matches this port over an ~ 10% bandwidth.

This insures good electrical and thermal grounding. If the IF AMP is run at Idss (DC Grounded IF BIAS pin 14), this pin should be grounded as described above. It is recommended that a continuous ground plane be present under the package to lower pin impedance and maintain similarity with the matching environment used in the schematic in the Application Information section. Bias for the IF amplifier is supplied thru IF OUT pin 14. All ports are DC coupled to the IC. Pins 2,6 and 13 should be kept at 0V DC to maintain proper gate voltages. Pin 9 is internally biased at 5V under normal operation and requires an external DC block.
