HMC684LP4 / 684LP4E
v03.0110
BiCMOS MMIC MIXER W/ INTEGRATED
LO AMPLIFIER, 700 - 1000 MHz
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 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 package.
8, 10, 24
Vcc1, Vcc2,
Vcc3
Power supply voltage. See application circuit
for required external components.
9 LO_BIAS
Adjust the LO buffer current through an external
resistor. See application circuit for required external
components.
16 LO
This pin is matched single-ended 50 Ohm and DC
shorted to ground through a balun.
19 G_BIAS
External optional bias. See application circuit
for required external components.
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.

BiCMOS MMIC MIXER W/ INTEGRATED
LO AMPLIFIER, 700 - 1000 MHz
Evaluation PCB
The circuit board used in the 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 Hit-
tite upon request.
