General Description
The HMC400MS8 & HMC400MS8E are high dynamic
range passive MMIC mixers in plastic surface mount
8 lead Mini Small Outline Packages (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 single-
ended 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 & HMC400MS8E 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.
Electrical Specifications, TA = +25°C, LO = +17dBm, IF = 200 MHz*
