• Manufacturer Part Number: OQ2538HP_97
• Description: SDH/SONET main amplifier
• Manufacturer: PHILIPS [NXP Semiconductors]

Philips Semiconductors
Although the differential voltage gain of the OQ2538HP
cannot be measured directly, it can be calculated from S
The differential voltage gain is 6 dB greater than the
measured S
100
differential voltage gain is increased by a further 2.4 dB,
typically to 48.4 dB. This is due to the fact that the output
load is increased from 25 to 33 , so the output voltage is
increased by a factor of 1.32 (2.4 dB).
