Tx Gain

(1) The HPA net Tx gain manufacturing tolerance (unit to unit), Tx Input port to Tx Output
port, is 54 dB ± 2 dB under conditions of:
(a)
(b)
(c)
(d)
(e)
(2) While the PA function is held in the disabled state the HPA net Tx gain capability, Tx input
port to Tx output port, is < -20 dB under conditions of 0 dB input attenuator back-off.
C.

Tx Frequency Response

(1) The Tx-band gain tolerance as assessed from the transmit port input to the transmit port
output is less than 1 dB peak to peak under conditions of:
(a)
(b)
(c)
D.

Tx Gain Stability

The per unit gain stability for any set level is better than ±1.5 dB due to combined
(1)
variations in temperature and frequency
(2) The output power stability is within ± 0.5 dB over the burst period excluding the first burst
and the preamble/training period of all subsequent bursts under the following conditions:
(a)
(b)
(c)
(d)
(e)
