* Unless otherwise noted all measurements performed as downconverter with low side LO & IF = 300 MHz.
The HMC666LP4(E) is Ideal for:
• WiMAX/4G & Fixed Wireless
• Infrastructure & Repeaters
• Transmitters & Receivers
• Test & Measurement Equipment
The HMC666LP4(E) is a high dynamic range
passive MMIC mixer with integrated LO ampliîšžer
in a 4x4 SMT QFN package covering 3.1 - 3.9
GHz. Excellent input IP3 performance of +31
dBm for down conversion is provided for WiMAX
and îšžxed wireless applications at an LO drive of
0 dBm. The LO port is optimized for low side LO
applications. With an input 1 dB compression of +23
dBm, the RF port will accept a wide range of input
signal levels. Conversion loss is 9 dB typical. The
DC to 800 MHz IF frequency response will satisfy
WiMAX transmit or receive frequency plans. The
HMC666LP4(E) is pin for pin compatible with the
HMC688LP4(E) which is a 2.0 - 2.7 GHz mixer with
LO ampliîšžer.
High Input IP3: +31 dBm
Low Conversion Loss: 9 dB
Low LO Drive: 0 dBm

Evaluation PCB
The circuit board used in the 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 Hit-
tite upon request.
