ACA2601
FTTH/FTTP RF Amplifiers
Application:
Fiber-to-the-Home RF Amplifier
Description:
The ANADIGICS ACA2601 amplifier for Fiber-to-the-Home (FTTH) applications is intended to be used in conjunction with the triplexer in fiber-coax line terminals. The device is driven by, and amplifies the output of, the video downstream path photodiode.
The high-impedance input of ACA2601 eliminates the need for a costly transformer usually needed to interface to the photodiode, and a low equivalent input noise level offers excellent sensitivity. The device provides sufficient linearity to maintain low CTB and CSO levels in full-bandwidth (132 channel) systems, even across a wide gain adjustment range.
The ACA2601 is manufactured using ANADIGICS' proven MESFET technology that offer state-of-the-art reliability, temperature stability, and ruggedness. The device operates from a single +5 V supply and is offered in a 5 mm x 5 mm x 1 mm surface mount package.
Features:
- 50-870 MHz Operating Frequency
- High Linearity: 65 dBc CTB/CSO (79 Chan.)
- Low Equivalent Input Noise: 4.5 pA/rtHz
- 20 dB Gain Adjust
- 400Ω Differential Input Impedance: No Transformer Required for Interface to Photodiode
- Single +5 V Supply
- 5 mm x 5 mm x 1 mm Surface Mount Package
- RoHS Compliant Package
