General Description
The HMC485MS8G & HMC485MS8GE are high dy-
namic range passive MMIC mixers with integrated
LO amplifier in plastic surface mount 8 lead Mini
Small Outline Packages (MSOP) covering 1.7 to 2.4
GHz. Excellent input IP3 performance of +34 dBm
for down conversion and +27 dBm for up conver-
sion is provided for 2.5G & 3G GSM/CDMA based
UMTS or PCS applications at an LO drive of 0 dBm.
With an input 1 dB compression of +19 dBm, the
RF port will accept a wide range of input signal lev-
els. Conversion loss is 9.2 dB typical. The 50 to 300
MHz IF frequency response will satisfy many UMTS/
PCS transmit or receive frequency plans configured
for low side LO. The HMC485MS8G(E) input IP3
performance coupled with its high P1dB rivals tradi-
tional active FET mixers while offering a much smaller
14.8mm2 standard IC footprint.
