| v01.1003 MICROWAVE CORPORATION HMC387MS8 HIGH IP3 GaAs MMIC MIXER, 450 - 500 MHz Features +32 dBm Input IP3 Conversion Loss: 9.5 dB Low External Part Count Ultra Small MSOP8 Package: 14.8 mm2 Typical Applications High Dynamic Range Infrastructure: * GSM 450 & GSM 480 * CDMA 450 * Private Land Mobile Radio 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. 12 MIXERS - SMT Electrical Specifications, TA = +25C, LO = +17 dBm, IF = 70 MHz* Parameter Frequency Range, RF Frequency Range, LO** Frequency Range, IF Conversion Loss Noise Figure (SSB) LO to RF Isolation LO to IF Isolation IP3 (Input) 1 dB Gain Compression (Input) LO Input Drive Level (Typical) 17 20 29 19 Min.
