TGA4832

Qorvo's TGA4832 is a medium power wideband AGC amplifier which operates from DC to 35 GHz. Typical small signal gain is 12 dB with 3 dB AGC range. Typical input and output return losses are > 10dB. The TGA4832 provides 18 dBm of output power at 1 dB gain compression.

Drain bias may be applied through the output port for best efficiency or through the on-chip drain termination. Two stages in cascade demonstrate 3.8 Vpp output voltage swing with 350 mV at the input when stimulated with 40 Gb/s 2^31-1 PRBS NRZ data. RF ports are DC coupled enabling the user to customize system corner frequencies. The TGA4832 requires off-chip decoupling and blocking components.

The TGA4832 is suitable for a variety of wideband electronic warfare (EW) systems such as radar warning receivers, electronic counter measures (ECM), decoys, and jammers. It is also an excellent choice for 40Gb/s NRZ applications. The TGA4832 is capable of driving an Electro-Absorptive optical Modulator (EAM) with electrical Non-Return to Zero (NRZ) data. In addition, the TGA4832 may also be used as a predriver or a receive gain block.

Bond pad and backside metallization is gold plated for compatibility with eutectic alloy attachment methods as well as the thermocompression and thermosonic wire bonding processes. Each device is 100% DC and RF tested on-wafer to ensure performance compliance. The device is available in die form and is lead-free and RoHS compliant.
