Product Summary

The TGA8652-SL is a medium power wideband AGC amplifier combined with off-chip circuitry assembled in a surface mount package. The part typically provides 16 dB small signal gain with 6 dB AGC range. Typical input and output return loss is less than 10 dB. Typical Noise Figure is 2.5 dB at 3 GHz. Typical saturated output power is 25 dBm. Small signal 3 dB BW is 12 GHz with saturated power performance to 16 GHz. RF ports are DC coupled enabling the user to customize system corner frequencies. The applications of the TGA8652-SL include Mach-Zehnder Modulator Driver, Pre-Driver Description, Receiver AGC.
