Subscriber Amplification

Subsriber amplifier 8 way

Subscriber Amplifiers 4 way

Amplification at the subscriber premises has become increasingly segmented, highly dependent on the mix of services and the number of devices supported for a given home. To address these new demands, TriAccess Technologies has developed a complete line of products ideally suited for premises amplification requirements. From simple single port, video only amplification to full multiport, multi-service support, TriAccess provides the RFIC and RF switch products needed for home amplification.

TriAccess Technologies amplifiers provide a range of gain levels to meet the need for comparable output levels regardless of drop amplifier ports. The TAT7461 provides 16 dB of gain for traditional applications, while the TAT7430 provides 22 dB of gain for higher port count amplifiers.

For Voice over IP/Digital Voice applications, TriAccess Technologies offers a voice bypass function to provide the option of opening an alternative path for continuous voice transmission in the case of power outage. The TAT2112 75 Ohm RF switch with high isolation and low loss, provides an economic and reliable solid state alternative to large mechanical relays.

TriAccess Drop Amplifier IC Advantage

TriAccess Technology amplifiers are fabricated using GaAs pHEMT technology, using high Gm processes and optimized gate lengths. This provides excellent stability, return loss, and overall performance.

TAT7461

The TAT74621 provides unprecedented stability and return loss performance over temperature while meeting stringent SCTE and major MSO distortion requirements.  The part delivers excellent pHEMT levels of noise performance.

TAT7430

The TAT7430 is a 22 dB gain part ideal for providing the gain required for output of higher port count drop amplifiers.

TAT2112

The TAT2112 provides bypass switching for voice drop amplifier applications.  The TAT2112 is a single pull double throw switch built in native 75 Ohms.  It can be used in both single and dual switch configurations to bypass the drop amplifier IC during power outage.
