Functional Diagram
General Description
The HMC685LP4(e) is a high dynamic range passive
MMiC mixer with integrated LO amplifier in a 4x4 sMT
QFN package covering 1.7 to 2.2 GHz. excellent input
iP3 performance of +35 dBm for down conversion is
provided for 3G & 4G GsM/CDMA applications at an
LO drive of 0 dBm. With an input 1 dB compression
of +27 dBm, the rF port will accept a wide range of
input signal levels. Conversion loss is 8 dB typical.
The DC to 500 MHz iF frequency response will sat-
isfy GsM/CDMA transmit or receive frequency plans.
The HMC685LP4(e) is pin for pin compatible with the
HMC684LP4(e) which is a 700 - 1000 MHz mixer with
LO amplifier.
