Quick Start
The following procedures allow for proper device
evaluation.
Required Test Equipment
• Regulated power supply capable of providing
+3.3V
• RF signal generator capable of delivering from
-120dBm to 0dBm of output power at the operating
frequency, in addition to AM or pulse-modulation
capabilities (Agilent E4420B or equivalent)
• Optional ammeter for measuring supply current
• Oscilloscope
Connections and Setup
This section provides a step-by-step guide to operating
the EV kit and testing the device’s functionality. Do not
turn on the DC power or RF signal generator until all
connections are made:
1) Connect a DC supply set to +3.3V (through an
ammeter if desired) to the VDD and GND terminals
on the EV kit. Do not turn on the supply.
2) Connect the RF signal generator to the RF_IN SMA
connector. Do not turn on the generator output. Set
the generator for an output frequency of 315MHz
(or 433.92MHz) at a power level of -100dBm. Set
the modulation of the generator to provide a 2kHz,
100%, AM-modulated square wave (or a 2kHz
pulse-modulated signal).
3) Connect the oscilloscope to test point TP3.
4) Turn on the DC supply. The supply current should
read approximately 5mA.
5) Activate the RF generator’s output without modula-
tion. The scope should display a DC voltage that
varies from approximately 1.2V to 2.0V as the RF
generator amplitude is changed from -115dBm to
0dBm. (Note: At an amplitude of around -60dBm,
this DC voltage drops suddenly to approximately
1.5V and then starts rising again with increasing
input amplitude. This is normal; the AGC is turning
on the LNA gain-reduction resistor.)
6) Set the RF generator to -100dBm. Activate the RF
generator’s modulation and set the scope’s cou-
