ELECTRICAL CHARACTERISTICS
Static sensitive electronic devices. Do not operate or store near strong electrostatic, fields. Take
proper ESD precautions. Stresses in excess of the absolute ratings may cause permanent damage.
Functional operation is not implied under these conditions. Exposure to absolute ratings for
extended periods of time may adversely affect reliability.

ELECTRICAL CHARACTERISTICS
Table 2: Electrical Specifications
(Pin < 3dBm, VD 1, 2, 3=+3.5 V; VREG = 3.1V; VSS = (-) 3V, Set VBC (Pin 3) to get IDQ of 150mA; TC = 25
°C, 50W Input/50W external output match)*
* As measured in ANADIGICS test fixture.
Recommended Operating Procedure on the
Evaluation Board
Power Up
A. Begin by setting all power supplies to 0.0 Volts.
B. Make sure that the RF input power is turned off.
C. Turn on VSS (Pin 3) to (-) 3V.
D. Turn VDS1 (Pin 1), VDS2 (Pin 9), VDS3 (Pins 11, 12,
13 and 14) and VDDC (Pin 4) which are tied
together on the fixture, and set to +3.5V and
set VREF (Pin 3) for IDQ of 150mA
E. Turn RF on and adjust input power to get
POUT = 28.5 dBm.
Power Down
To power down the device follow the above procedure
in reverse order.
Procedure for Amplifier Operation and Test
1) Slug must be thermally and electrically
connected to obtain rated performance.
2) The VSS Voltage should be applied first to the
amplifier prior to VD1, VD2, or VD3 voltages.
3) The Bias Pins VREG and VBC may be applied with
no VSS voltage present.
4) Always follow ESD precautions when handling
these devices.
