The CATV amplifier has wide-band and low noise and high linearity (CSO,
CTB) feature over 5-1000 MHz; 5-400 MHz and 50-1000 MHz. For various
requirement of the market, it provides various application circuits;
the flat gain, the positive gain slope, the lowest return loss, and the
lowest DC power consumption, etc. For use in SMATV, the design
reference circuit at 960-2160 MHz is also provided.
Push-pull application is provided in order to have higher linearity than the single chip application.

* ASL522 : Preliminary Data. Engineering sample is available.
* (P-P) means two chips in push-pull configuration.
1) For 116 flat channels at the input, measured at the output were 77 analog channels (55 MHz to 550 MHz) @ +20 dBmV per channel and 39 digital channels (550 MHz to 750 MHz) @ 6 dB lower than that of the analog channel.
2) 160 channels, +20 dBmV per channel (measured at output).
3) 60 channels, +42 dBmV per channel (measured at output), measured at 543.25MHz.
