TriQuint Semiconductor has released a highly-flexible, single-ended amplifier 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.

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.
