General Description
The HMC485MS8G is a high dynamic range
passive MMIC mixer with an integrated LO amplifier
in a plastic surface mount 8 lead Mini Small
Outline Package (MSOP) covering 1.7 to 2.2 GHz.
Excellent input IP3 performance of +34 dBm for
down conversion and +27 dBm for up conversion
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
levels. 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
input IP3 performance coupled with its high P1dB
rivals traditional active FET mixers while offering
a much smaller 14.8mm² standard IC footprint.
