Functional Diagram
General Description
The HMC485MS8G is a high dynamic range passive MMIC mixer with an integrated LO amplifier in a plastic surface mount 8 lead Mini Small Outline Package (MSOP) covering 1.7 to 2.2 GHz. Excellent input IP3 performance of +34 dBm for down conversion and +27 dBm for up conversion is provided for 2.5G & 3G GSM/CDMA based UMTS or PCS applications at an LO drive of 0 dBm. With an input 1 dB compression of +19 dBm, the RF port will accept a wide range of input signal levels. Conversion loss is 9.2 dB typical. The 50 to 300 MHz IF frequency response will satisfy many UMTS/PCS transmit or receive frequency plans configured for low side LO. The HMC485MS8G input IP3 performance coupled with its high P1dB rivals traditional active FET mixers while offering a much smaller 14.8mm2 standard IC footprint.

The circuit board used in the final application should use RF circuit design techniques. Signal lines should have 50 ohm impedance while the package ground leads and exposed paddle should be connected directly to the ground plane similar to that shown. A sufficient number of VIA holes should be used to connect the top and bottom ground planes. The evaluation circuit board shown is available from Hittite upon request.
