TriQuint Semiconductor Inc., an RF products manufacturer and foundry services provider, has released a highly-flexible single-ended amplifier at the SCTE Cable-Tec Expo in New Orleans, LA. The new product is ideal for subscriber/premises applications, including optical network units (ONU), Ethernet over Coax (EoC) distribution and a variety of existing and emerging home amplifier designs, offering a degree of flexibility not found in other market solutions.

The TAT7457 nominally provides 19 dB gain, yet through an off-chip feedback resistor it can also provide variable gain adjustment, trading off the 120 mA (at 5 V) typical current, making it ideal for home network amplification requirements. It offers higher gain, superior distortion and better return loss compared to 16 dB amplifiers traditionally used in home network applications. The TAT7457 is designed to be highly economical, priced below $0.45/each in quantities over 100,000 units; contact product marketing for TAT7457 samples and evaluation board requests.

“TriQuint’s TriAccess™ CATV/FTTH products satisfy and simplify RF needs in high-speed broadband systems,” said Brian Bauer, TriQuint CATV Product Marketing Manager. “Our newest device, TAT7457, offers the flexibility that engineers haven’t found it other home network products. Our DOCSIS® 3.0/Edge QAM amplifiers can cut power consumption by 50% and space by 80 percent. Our FTTH/GPON/RFoG amplifiers deliver the ultra low noise performance needed to substantially extend system link budgets.”
