* Unless otherwise noted all measurements performed as downconverter with low side LO & IF = 100 MHz.

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
