General Description
The HMC387MS8 & HMC387MS8E are high dynamic
range passive MMIC mixers in plastic surface mount
8 lead Mini Small Outline Packages (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 cel-
lular transmit or receive frequency plans. The
HMC387MS8 & HMC387MS8E input IP3 performance
coupled with its high P1dB rivals traditional active
FET mixers while offering a much smaller 14.8mm
2
standard IC footprint and no DC bias.
