The HMC400MS8 is a high dynamic range passive MMIC mixer in a plastic surface mount 8 lead Mini Small Outline Package (MSOP) covering 1.7 to 2.2 GHz. Excellent input IP3 performance of +36 dBm for down conversion and +29 dBm for up conversion is provided for 2.5G & 3G GSM/CDMA based UMTS or PCS applications at an LO drive of +17dBm. With a 1dB compression of +21 dBm, the RF port will accept a wide range of input signal levels. Conversion loss is 8.5dB typical and LO isolations are maintained at 22 to 33 dB. This miniature singleended monolithic GaAs FET mixer does not require any external components or bias. The 50 to 300 MHz IF frequency response will satisfy many UMTS/PCS transmit or receive frequency plans configured for low side LO. The HMC400MS8 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.
