The TAT6281 variable gain receiver for single family units (SFUs) employs proven PIN diode variable attenuation to provide a consistent, low-distortion method of adjusting gain. The integrated module delivers reliable, low-noise RF performance while simplifying FTTH amplifier designs and reducing bills of materials (BOMs).

The TAT6281 45- to 1003-MHz variable gain receiver features 8-dB pA/rtHz typical EIN. It requires a 5-V at 220 mA bias supply and includes 20 dB PIN diode variable gain attenuator. The receiver offers 18 dB typical and 37 dB maximum gain, 18 dB return loss, 8 to + 1-dBm optical input range, 20 dBmV RF output and comes in a 6- x 6-mm leadless SMT package.

TriQuint’s TAT2814A 45- to 1003-MHz fully integrated two stage amplifier satisfies the DOCSIS® 3.0 specification with more than 4 dB (typical) performance margin. By integrating two stages of amplification and a variable gain attenuator, it can greatly simplify CATV RF design by reducing the number of discrete RF components. Other solutions require up to five-times the PCB space to deliver DOCSIS 3.0 performance while consuming up to twice the electrical power.

The TAT2814A features <5 W nominal power consumption, low-reflection differential input/output stages, 30 dB typical maximum gain, 4.5 typical noise figure, and comes in a 6-x 6-mm leadless SMT package.

The TAT2814A is ideal for DOCSIS 3.0 output stage amplifier designs including Edge QAM and CMTS (cable modem termination system) applications. It is also ideally suited for Ethernet over Coax (EOC) supporting DOCSIS 3.0 PA levels.
