* Unless otherwise noted, all measurements performed as a downconverter with low side LO & IF = 200 MHz
** LO Frequency optimized. See application circuit herein.
The HMC399MS8 is a high dynamic range passive
MMIC mixer in a plastic surface mount 8 lead Mini
Small Outline Package (MSOP) covering 700 to 1000
MHz. Excellent input IP3 performance of +35 dBm
for down conversion and +32 dBm for up conversion
is provided for 2.5G & 3G GSM/CDMA based cellular
applications at an LO drive of +17dBm. With a 1 dB
compression of +23 dBm, the RF port will accept a
wide range of input signal levels. Conversion loss is
8.5 dB typical and LO isolations are maintained at
23 to 35 dB. This miniature single-ended monolithic
GaAs FET mixer requires only one external inductor
to optimize the LO frequency response. The 50 to
250 MHz IF frequency response will satisfy many
cellular transmit or receive frequency plans. The
HMC399MS8 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.
