ASL550

Wideband Linear Amplifier MMIC

.

1) OIP3 is measured with two tones at an output power of +10 dBm/tone separated by

6 MHz.

2) OIP2 is measured at F1+F2 Frequency.

3) 116 total channels, flat input; 77 analog channels (55 MHz to 550MHz) @ +20 dBmV

per channel; 39 digital channels (550 MHz to 750 MHz) @ 6 dB below analog channels,

measured at 335.25 MHz.
