1. The slope is defined as the difference between the gain at the start frequency and the gain at the stop frequency.

2. 79 analog channels, NTSC frequency raster: 55.25MHz to 547.25MHz, +43dBmV to +52.4dBmV tilted output level, plus 75 digital channels, -6dB offset

relative to the equivalent analog carrier.

3. 79 analog channels, NTSC frequency raster: 55.25MHz to 547.25MHz, +43dBmV to +50.0dBmV tilted output level, plus 75 digital channels, -6dB offset

relative to the equivalent analog carrier.

4. Composite Triple Beat (CTB) - The CTB parameter is defined by the NCTA.

Composite Second Order (CSO) - The CSO parameter (both sum and difference products) is defined by the NCTA.

Cross Modulation (XMOD) - Cross modulation (XMOD) is measured at baseband (selective voltmeter method), referenced to 100% modulation of the

carrier being tested.

Carrier to Intermodulation Noise (CIN) - The CIN parameter is defined by ANSI/SCTE 17 (Test Procedure for carrier to noise).

5. Test condition: Pin 4 not connected

Current Adjustment Using Hybrid Pin 4

The RFPD2650 can be operated over a wide range of current to provide maximum required performance with minimum current

consumption. A single external resistor connected between pin 4 and GND allows variation of current between 430mA and 220mA

(typ.). Within the recommended range of current between 430mA and 370mA gain (S21) change is less than 0.2dB and noise

figure change is less than 0.1dB. If pin 4 is not connected the devices operates at maximum current, see table below.

Examples of connecting pin 4:
