General Description
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.
