Supply Current Icc total 140 168 mA
* Unless otherwise noted all measurements performed as downconverter with low side LO & IF = 300 MHz.
The HMC688LP4(E) is Ideal for:
• Cellular/3G & LTE/WiMAX/4G
• Basestations & Repeaters
• GSM, CDMA & OFDM
• Transmitters and Receivers
The HMC688LP4(E) is a high dynamic range passive
MMIC mixer with integrated LO amplier in a 4x4 SMT
QFN package covering 2.0 to 2.7 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 +25 dBm, the RF port will accept a wide range of
input signal levels. Conversion loss is 7.5 dB typical.
The DC to 700 MHz IF frequency response will satisfy
GSM/CDMA transmit or receive frequency plans.
The HMC688LP4(E) is pin for pin compatible with the
HMC689LP4(E) which is a 2.0 - 2.7 GHz mixer with
LO amplier optimized for high side LO applications.
High Input IP3: +35 dBm
Low Conversion Loss: 7.5 dB
Low LO Drive: 0 dBm
Optimized for Low Side LO Input
