v01.1003 MICROWAVE CORPORATION HMC387MS8 HIGH IP3 GaAs MMIC MIXER, 450 - 500 MHz Typical Applications Features High Dynamic Range Infrastructure: +32 dBm Input IP3 • GSM 450 & GSM 480 Conversion Loss: 9.5 dB • CDMA 450 Low External Part Count • Private Land Mobile Radio Ultra Small MSOP8 Package: 14.8 mm2 Functional Diagram General Description The HMC387MS8 is a high dynamic range passive MMIC mixer in a plastic surface mount 8 lead Mini Small Outline Package (MSOP) covering 450 to 500 MHz. Excellent input IP3 performance of +32 dBm for down conversion and +29 dBm for up conversion is provided for both GSM/CDMA based cellular and Private Land Mobile Radio applications at an LO drive of +17dBm. The mixer also has excellent performance with as little as +13 dBm LO drive yielding a +30 dBm input IP3. With a 1 dB compression of +22 dBm, the RF port will accept a wide range of input signal levels. Conversion loss is 9.5 dB typical. The DC to 150 MHz IF frequency response will satisfy many cellular transmit or receive frequency plans. The HMC387MS8 input IP3 performance coupled with its high P1dB rivals traditional active FET mixers while offering a much smaller 14.8mm2 standard IC footprint and no DC bias.
