Two TriAccess amplifiers designed to replace multiple products in cable-TV systems are on display by TriQuint Semiconductor Inc. at this week’s ANGA Cable Show in Germany. The devices were built using gallium arsenide (GaAs) technology.

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

More TAT6281 specs: 45 MHz to 1003 MHz variable gain receiver; 8dB pA/rtHz typical EIN; 5V @ 220 mA bias supply; 20dB PIN diode variable gain attenuator; 18dB typical and 37dB maximum gain; 18dB return loss; 8 to + 1dBm optical input range; 20dBmV RF output; 6x6mm leadless SMT package. Samples available July 27, 2012.

The TAT2814A complies with DOCSIS 3.0, offering more than 4 dB (typical) margin. By integrating two stages of amplification and a variable gain attenuator, the TAT2814A can help 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.

More TAT2814A specs: 45 MHz-1003 MHz; integrated two-stage amp with variable gain attenuator; meets DOCSIS 3.0 with +4 dB typical performance margin; <5 Watt nominal power consumption; low-reflection differential input/output stages; 30dB typical max gain; 4.5 typical noise figure; 6x6mm leadless SMT package. Samples now available.

The TAT2814A also can be deployed for Ethernet over Coax (EOC) supporting DOCSIS 3.0 PA levels.
