TAT6254C
Fiber To The Home RF Amplifier 47–1000 MHz
Gain control is accommodated with a low cost external PIN diode circuit placed between the input trans-impedance amplifier
and the output amplifier. This helps reduce the die size of the TAT6254C and provides for excellent PIN diode distortion
characteristics over a continuous control range.
Up to 33 dB of gain control is possible using the recommended 12 V standard output application circuit.
The application circuits are optimized for 870 MHz performance with slight rolloff for use in combination with a post filter for
applications such as MoCA. For optimized performance at 1 GHz and beyond, it is recommended that a low capacitance
photodiode be used with a change in value of the peaking inductors L1 and L2. For further guidance, please contact TriQuint
Semiconductor Application Engineering.
For high output operation, refer to the appropriate 5 V high output application circuit. This option uses a 4:1 transformer to
combine the outputs of the second stage.
