GaAs amplifiers from TriQuint for CATV/FTTH applications

TriQuint Semiconductor has announced the availability of two new TriAccess amplifiers TAT6281 and TAT2814A designed to replace multiple products in CATV systems. These devices are built with gallium arsenide (GaAs) technology and offers better functional integration and efficiency.
The TAT6281 variable gain receiver for single family units (SFUs) use PIN diode variable attenuation to provide a consistent, low-distortion method of adjusting gain. The module simplified the FTTH design.

Specifications of TAT6281:
1. 45 to 1003 MHz variable gain receiver
2. 8dB pA/rtHz typical EIN
3. 5V @ 220 mA bias supply
4. 20dB PIN diode variable gain attenuator
5. 18dB typical and 37dB maximum gain
6. 18dB return loss
7. 8 to + 1dBm optical input range
8. 20dBmV RF output
9. 6x6 mm leadless SMT package

The TAT2814A meets the DOCSIS 3.0 specification with 4dB (typical) margin. The solution is suitable for DOCSIS 3.0 output stage amplifier designs including Edge QAM and CMTS (cable modem termination system) applications. The module is suits for Ethernet over Coax (EOC) supporting DOCSIS 3.0 PA levels.

Specifications of TAT2814A:

1. 45-1003 MHz
2. Fully integrated two stage amplifier with variable gain attenuator
3. <5 Watt nominal power consumption
4. Low-reflection differential input/output stages
5. 30dB typical max gain
6. 4.5 typical noise figure
7. 6x6 mm leadless SMT package

Samples of TAT6281 are available from July 27, 2012 while the samples of TAT2814A are available now.
