General Description
The HMC685LP4(E) is a high dynamic range passive
MMIC mixer with integrated LO amplifier in a 4x4 SMT
QFN package covering 1.7 to 2.2 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 +27 dBm, the RF port will accept a wide range of
input signal levels. Conversion loss is 8 dB typical.
The DC to 500 MHz IF frequency response will sat-
isfy GSM/CDMA transmit or receive frequency plans.
The HMC685LP4(E) is pin for pin compatible with the
HMC684LP4(E) which is a 700 - 1000 MHz mixer with
LO amplifier.
Electrical Specifications,
TA = +25° C, IF = 200 MHz, LO = 0 dBm, Vcc = Vcc1, 2, 3 = +5V, G_Bias = +2.5V*
