[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 amplier 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.
High Input IP3: +34 dBm
7.5 dB Conversion Loss @ 0 dBm LO

Pin Number Function Description Interface Schematic
1, 6, 7, 11 - 14,
18, 20, 23 N/C No connection. These pins may be connected to RF
ground. Performance will not be affected.
2, 5, 15, 17 GND Package bottom must be
connected to RF/DC ground.
3 RF This pin is matched single-ended to 50 Ohms and DC
shorted to ground through a balun.
4 TAP Center tap of secondary side of the internal RF balun.
Short to ground with zero ohms close to the package.
8, 10, 24 Vcc1, Vcc2,
Vcc3
Power supply voltage. See application circuit
for required external components.
9 LO_BIAS
LO buffer current adjustment pin. Adjust the LO buffer
current through the external resistor R9 shown in the
application circuit (connect 330 Ohms for nominal
operation). This adjustment allows for a trade-off
between power dissipation and linearity performance of
the converter.
16 LO This pin is matched single-ended to 50 Ohms and DC
shorted to ground through a balun.
19 G_BIAS
External bias. See application circuit for recom-
mended external components. Apply +3.5V for nominal
operation at 5V supply voltage. G_Bias can be set to
between 0 and 5Vdc. The G_bias pin has an internal
15K ohm resistance to ground. This adjustment allows
for a trade off between conversion loss and linearity
performance of the converter (see gures CG, IP3 vs.
G-Bias).
21, 22 IFN, IFP
Differential IF input / output pins matched to differential
50 Ohms. For applications not requiring operation to
DC an off chip DC blocking capacitor should be used.
