The Communications Edge TM HMJ9 High Dynamic Range FET Mixer The Communications Ed * Product Features * * * * * * * * +35 dBm IIP3 No External Matching Elements Required RF 860-900 MHz LO 1140-1160 MHz IF 250-280 MHz +17 dBm Drive Level +3V Bias (23 mA) Low Cost Surface Mount J-Lead Package Functional Diagram Product Description The HMJ9 is a high dynamic range, GaAs FET mixer. As an upconverter, this active FET mixer realizes a typical third order intercept point of +35 dBm at an LO drive level of +17 dBm. The HMJ9 comes in a low cost, J-lead package. Typical applications include frequency up/down conversion for receivers and transmitters used in cellular communications systems.
