Functional Diagram
General Description
The HMC686LP4(e) is a high dynamic range passive
MMiC mixer with integrated LO amplifier in a 4x4
sMT QFN package covering 0.7 to 1.1 GHz. excellent
input iP3 performance of +34 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 7.5 dB
typical. The DC to 500 MHz iF frequency response
will satisfy GsM/CDMA transmit or receive frequ-
ency plans. The HMC686LP4(e) is optimized to high
side LO frequency plans for 0.7 - 1.1 GHz rF Band
and is pin for pin compatible with the HMC684LP4(e)
which is a 0.7 - 1.0 GHz converter optimized for low
side LO. The HMC686LP4(e) is optimized to low side
LO frequency plans for 1.4 - 1.5 GHz rF LTe band
applications.
