[1] Unless otherwise noted all measurements performed for 0.7 - 1.1 GHz rF band as downconverter with high side LO & iF = 150 MHz,

icc = 105 mA, G_Bias = 3.5 V

[2] Unless otherwise noted all measurements performed for 1.4 - 1.5 GHz rF LTe band as downconverter with low side LO & iF = 140 MHz

The HMC686LP4(e) is ideal for:

• Cellular/3G & LTe/WiMAx/4G

• Basestations & repeaters

• GsM, CDMA & OFDM

• Transmitters and receivers

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.
