For AM gain measurement, Required Test Equipment connect the generator output to the AMIN SMA RF signal generator (or generators) capable of connector on the EV kit. For FM gain measurement, delivering a signal in the 200kHz to 30MHz (AM) range, connect the generator output to the FMIN SMA or 76MHz to 162.5MHz (FM) range at a power level of connector on the EV kit. -34dBm.(A high er power source is required to mea- 3) For FM gain measuremen t, connect an SMA cable sure distortion performance.

The signal on the Ammeter to measure supply current (optional) spectrum analy zer s display should indicate a typical Noise-figure meter to measure NF (optional) gain, as shown on the MAX2180A IC data sheet after Network analyzer to measure gain and return loss accounting for cable and board losses. (optional) 6) Optional: Another method of determining gain is by using a network analyzer. This has the advantage Connections and Setup of displ aying gain versus a swept frequency band, Checking Gain in addition to displaying input and output return loss. The EV kit is fully assembled and factory tested. Follow Refer to the user manual of the network analyzer for the steps below for proper device evaluation in the default setup information. configuration. 1) Conn ect a DC supply (preset to +10V) to the VBATT and GND terminals (through an ammeter, if desired) on the EV kit.
