Quick Start
The following procedure allows for proper device
evaluation.
Required Test Equipment
Regulated power supply capable of providing +3.0V
Spectrum analyzer such as the Agilent 8562E
Optional ammeter for measuring supply current
Power meter such as the Agilent EPM-441A
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 until all connections are made:
1)
Connect a DC supply set to +3.0V, through an
ammeter, to the VDD and VSS terminals on the EV
kit. Do not turn on the supply.
2)
Connect the RF_OUT SMA connector to the spec-
trum analyzer. Set the analyzer to a center frequency
of 315MHz (or 433.92MHz) and a span of 1MHz.
3)
Turn on the DC supply. The spectrum analyzer
should display a peak of about +10dBm at
315MHz (or 433.92MHz).
4)
Disconnect the spectrum analyzer and connect
the power meter instead. Measure the output
power and also the current draw.
5)
Calculate the efficiency. This is done using the
following equation:
Efficiency = 10
(P
OUT
/10)/(V x I)
For example, for a +10.8dBm output, and a
10.9mA (at 3.0V) current, the efficiency is 37%.
