The HMC684LP4(e) is ideal for:

• Cellular/3G & LTe/WiMAx/4G

• Basestations & repeaters

• GsM, CDMA & OFDM

• Transmitters and receivers

The HMC684LP4(e) is a high dynamic range passive

MMiC mixer with integrated LO amplifier in a 4x4

sMT QFN package covering 0.7 to 1.0 GHz. excellent

input iP3 performance of +32 dBm for down conver-

sion is provided for 3G & 4G GsM/CDMA applications

at an LO drive of 0 dBm. With an input 1 dB com-

pression of +25 dBm, the rF port will accept a wide

range of input signal levels. Conversion loss is 7 dB

typical. The DC to 450 MHz iF frequency response

will satisfy GsM/CDMA transmit or receive frequency

plans. The HMC684LP4(e) is pin for pin compatible

with the HMC685LP4(e) which is a 1.7 - 2.2 GHz mixer

with LO amplifier.

High input iP3: +32 dBm

Low Conversion Loss: 7 dB

Low LO Drive: 0 dBm
