QPA3248
® CATV Power Doubler Hybrid 1003MHz 25dB
Product Description
The QPA3248 is a Hybrid Power Doubler amplifier
module. The part employs GaAs/GaN die and is operated
from 45 MHz to 1003 MHz. It provides excellent linearity
and superior return loss performance with low noise and
optimal reliability. DC current of the device can be
externally adjusted for optimum distortion performance
versus power consumption over a wide range of output
level.

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 ANSI/SCTE 6.
Composite Second Order (CSO) - The CSO parameter (both sum and difference products) is defined by ANSI/SCTE 6.
Cross Modulation (XMOD) - Cross modulation (XMOD) is defined by ANSI/SCTE 58, 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
6. Test condition: Pin 4 connected to GND via 2.4k resistor
Current Adjustment Using Hybrid Pin 4
The QPA3248 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 470mA and 150mA
(typ.). Within the recommended range of current between 470mA 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.
