Test conditions unless otherwise noted: V+ = 34V; TMB = 35°C; ZS = ZL = 75Ω CTB -80 -73 dBc VO = 63 dBmV at 1218MHz, 22dB extrapolated tilt, 79 analog channels plus 111 digital channels (-6dB offset)[2][3] XMOD -75 -68 dBc CSO -80 -74 dBc CIN 58 55 dB 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, +41 dBmV to +50.4 dBmV tilted output level, plus 111 digital channels, - 6dB offset relative to the equivalent analog carrier. 3. Composite Second Order (CSO) - The CSO parameter (both sum and difference products) is defined by ANSI/SCTE 6. Composite Triple Beat (CTB) - The CTB parameter is defined by ANSI/SCTE 6. 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).

RFMD + TriQuint = Qorvo Power Supply Adjustment The RFPD3580 can be operated at a power supply voltage V+ between 24V and 34V to provide maximum required linearity performance at minimum power consumption. Maximum output capability can be adjusted between 73.8dBmV composite power (= 58dBmV actual level at fmax equivalent to 64dBmV virtual level) at V+ = 24V and 76.8dBmV composite power (= 61dBmV actual level at fmax equivalent to 67dBmV virtual level) at V+ = 34V under a pure digital loading (190 channels QAM256) with 22dB tilt.

RFMD + TriQuint = Qorvo Current Adjustment Using Hybrid Pin 4 The RFPD3580 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 530mA and 130mA (typ.). Within the recommended range of current between 530mA and 430mA gain (S21) change is less than 0.2dB and noise figure change is less than 0.1dB. If pin 4 is not connected the device operates at maximum current, see table below.
