Specification Notes
1) The 2809 receiver does not include an adjustable RF output level. The unit is
designed to give approximately an RF output of +18 dBmV per channel at an
optical input of 0 dBm. The RF level will change by 2 dB for every 1 dB
change in optical input. At an optical input of -8.0 dBm, the RF level will be
about +2 dBmV per channel. At an optical input of +4.5 dBm, the RF level
will be approxi27 dBmV per channel.
2) Figure 1.1 shows the typical frequency response of a 2806T/2809R link over
the specified frequency range. The gain flatness is ±1.5 dB over this range.
The flatness is typically less than ±0.1 dB over a standard 6 MHz channel
bandwidth. See Application Note AN123 for additional information on North
American Television Frequencies.
