Control on/off
The RF SUM AMP either adds or subtracts the input signal selected in the RF Multiplexer by the RFSUM_SEL
and compensates according to the I/V polarity using ADDRESS 00H's BUF_SEL, to produce the RF signal.
Also, the RF SUM AMP is able to adjust the LEVEL by the gain selected by GAIN_RFSUM (-6
–
-16dB).
The RF AGC circuit makes the signal whose gain was adjusted by the RFSUM AMP into a regular size. The
AGC circuit
'
s output size is selected according to the value of AGC_LVL (3.2V
–
3.75V), between 0.5Vpp --
1.25Vpp in increments of 0.25Vpp STEP. The AGC
'
s response time constant is decided by the resistance
capacity of the Capacitor connected to the external connection PIN (AGCP, AGCB, AGCC).
SW is prohibited the peaking by hold the AGC voltage when meet the defect or interruption
