relative to the equivalent analog carrier.Composite Second Order (CSO) - The CSO parameter (both sum and difference products) is
defined by the NCTA.Composite Triple Beat (CTB) - The CTB parameter is defined by the NCTA.Cross Modulation (XMOD) - Cross
modulation (XMOD) is measured at baseband (selective voltmeter method), referenced to 100% modulation of the car-rier being
tested.Carrier to Intermodulation Noise (CIN) - The CIN parameter is defined by ANSI/SCTE 17 (Test procedure for carrier to noise).

Current Adjustment Using Resistor R5
The RFCM3080 can be operated over a wide range of current to provide maximum required performance with minimum current consumption.
Changing the value of resistor R5 on application circuit allows a variation of the current between 200mA and 255mA (typ.). Within the range of
current between 200mA and 255mA gain (S21) change is less than 0.4dB and noise figure change is less than 0.1dB.

Evaluation Board Layout
Note:
The ground plane of the RFCM3080 module should be soldered onto a board equipped with as many thermal vias as possible. Underneath this
thermal via array a heat sink with thermal grease needs to be placed which is able to dissipate the complete module DC power (up to 6.5 Watts).
In any case the module backside temperature should not exceed 100°C.
