N/C
No connection necessary.
These pins may be connected to RF/DC ground.
2RFIN
This pin is matched to 50 Ohms with a 19 nH inductor to
ground. See Application Circuit.
4Vctl
DC ground return. LNA is in high gain mode when a short
circuit is introduced to this pin through an external switch.
LNA is in bypass mode when open circuit is introduced
6ACG
An external capacitor of 0.01μF to ground is required
for low frequency bypassing.
See Application Circuit for further details.
7, 14 GND These pins must be connected to RF/DC ground.
9Vdd
Power supply voltage. Choke inductor and bypass capacitor
are required. See application circuit.
11 RFOUT This pin is AC coupled and matched to 50 Ohms.

[1] Reference this number when ordering complete evaluation PCB
[2] Circuit Board Material: Rogers 4350
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
Hittite upon request.

Application Circuit
Note 1: Choose value of capacitor C1 for low frequency bypassing. A 0.01 μF ±10% capacitor is recommended.
Note 2: Pin 4 (Vctl) is the DC ground return for the circuit. The LNA is in the high gain mode when a short circuit is introduced to this
pin through an external switch. The LNA is in bypass mode when an open circuit is introduced. For the data presented, switching is
done through a two position DIP switch (J5) in series with a 2 Ohm resistor (to account for the Ron of an electrical switch).
Note 3: L1, L2 and C1 should be located as close to pins as possible.
