Qorvo QPL1841
The QPL1841 from Qorvo is a RF Amplifier with Frequency 5 to 850 MHz, Gain 12 to 12.5 dB, Noise Figure 2.6 to 2.9 dB, P1dB 19.5 to 21.5 dBm, Input Return Loss 20 dB. Tags: Surface Mount, CATV Amplifier, Gain Block. More details for QPL1841 can be seen below.
The QPL1841 from Qorvo is a GaAs CATV MMIC Amplifier that operates from 5 to 850 MHz. It delivers a gain of 12.5 dB and has a noise figure of less than 2.9 dB with an output P1dB of up to 21.5 dBm. This single-ended amplifier is manufactured using a GaAs pHEMT process and has a reverse isolation of 17 dB with a return loss of -20 dB (input/output). It requires a DC supply of 5 or 8 V and consumes less than 160 mA of current. This 75-ohm CATV amplifier is available in a 16-pin QFN package measuring 3 x 3 x 0.85 mm. It is designed for broadband CATV DOCSIS 4.0 applications, such as nodes, amplifiers, and remote PHY devices, as well as fiber to the home (FTTH), home gateways, and cable modems.

The Qorvo QPL1841 is a GaAs pHEMT single-ended MMIC RF amplifier IC featuring 12 dB of gain and low noise from 5 MHz to 850 MHz. This high-linearity IC is designed to support Broadband CATV DOCSIS 4.0 applications, including nodes, amplifiers, and Remote PHY devices, as well as Fiber to the Home (FTTH), home gateways, and cable modems. The combination of low noise, excellent distortion, and low gain makes it suitable for drop amplifiers and other distribution amplifiers. The device is powered by a single supply operating from 5 V to 8 V, with current set at 115 mA. At 5 V, the QPL1841 provides an output of 57 dBmV TCP with a CCN of 51 dB. The QPL1841 is packaged in a 3.0 x 3.0 mm, 16-pin QFN.
