[1] See Application Circuit [2] Unless otherwise noted all measurements with low side LO & IF = 100 MHz.
The HMC683LP6C(E) is Ideal for:
• Cellular/3G & LTE/WiMAX/4G
• Basestations & Repeaters
• GSM, CDMA & OFDM
• Dual Density Receivers
The HMC683LP6C(E) is a high linearity, dual channel
downconverter with integrated LO amplier in a 6x6
SMT QFN package covering 0.7 - 1.0 GHz. Excellent
input IP3 performance of +23 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 +11 dBm, the RF port will accept a wide range of
input signal levels. Conversion gain is 7.5 dB typical.
The 60 - 500 MHz IF frequency response will satisfy
various GSM/CDMA receive frequency plans.
High Input IP3: +23 dBm
Conversion Gain: 7.5 dB
Low LO Drive: 0 dBm

Evaluation PCB
The circuit board used in the nal application should use RF circuit design techniques. Signal lines should have
50 Ohm impedance while the package ground leads and exposed paddle should be connected directly to the
ground plane similar to that shown. A sufficient number of via holes should be used to connect the top and
bottom ground planes. The evaluation circuit board shown is available from Hittite upon request.
