* Unless otherwise noted all measurements performed as downconverter with low side LO & IF = 200 MHz.

The HMC685LP4(e) is ideal for:

• Cellular/3G & LTe/WiMAx/4G

• Basestations & repeaters

• GsM, CDMA & OFDM

• Transmitters and receivers

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.

High input iP3: +35 dBm

8 dB Conversion Loss @ 0 dBm LO

Optimized for Low side LO input
