General Description
The HMC214MS8 & HMC214MS8E are general
purpose high dynamic range passive MMIC mixers
in plastic surface mount 8 lead Mini Small Outline
Packages (MSOP) covering 2.4 to 4 GHz. Excellent input IP3 performance of +34 dBm for downconversion and +31 dBm for upconversion is provided
for WiMax and other 3.5 GHz applications at an
LO drive of +17 dBm. With a 1dB compression of
+22 dBm, the RF port will accept a wide range of
input signal levels. Conversion loss is 10 dB typical and LO isolations are maintained at 25 to 30 dB.
This miniature single-ended monolithic GaAs FET
mixer does not require any external components or
bias. The DC to 1 GHz IF frequency response will
satisfy many transmit and receive frequency plans
con gured for low side LO. The HMC214MS8 &
HMC214MS8E input IP3 performance coupled with
its high P1dB rivals traditional active FET mixers
while offering a much smaller 14.8mm
footprint and no DC bias.
