Product Summary

The Microtune MT1530 is a low-cost programmable-gain power amplifier IC for use in CATV upstream applications. Specifically, the MT1530 is optimized for the DOCSIS upstream standard. The device operates at a frequency range from 5 MHz to 65 MHz, and can output 64 dBmV through a 4:1 impedance-ratio transformer. Second harmonic distortion is typically less than -70 dBc, and third harmonic distortion is typically less than -55 dBc at a 59 dBmV output level. A 3-wire digital serial bus controls the variable gain, with gain control available in 1-dB steps and a nominal 63-dB gain range. The MT1530 may be disabled via an external control pin. The transmit-disable mode not only minimizes output noise by shutting off the output stage, but also maintains its output impedance at nominal levels. Output glitch transients are nominally less than 4 mV at maximum gain settings during transmit enable/disable switching.
