Functional Diagram
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 satisfy 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.

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 50 ohm and DC
shorted to ground through a balun.
4
TAP
Center tap of secondary side of the internal RF balun.
Short to ground with a zero ohm close to the IC.
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 270 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 50 ohm and DC
shorted to ground through a balun.
19
G_BIAS
External bias. See application circuit for recommended external components. Apply +2.5V 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 figures 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.

The circuit board used in the final application should
use RF circuit design techniques. Signal lines
should have 50 ohm impedance while the package
ground leads and exposed paddle should be connected directly to the ground plane similar to that
shown. A sufficient number of via holes should be
used to connect the top and bottom ground planes.
The evaluation circuit board shown is available from
Hittite upon request.
