The TriQuint TGA4830 is a medium power wideband low noise amplifier (LNA) which operates from DC to 45 GHz. Typical small signal gain is 13 dB with > 20dB AGC range. Typical input and output return loss is 15 dB. The TGA4830 provides 11.5 dBm of typical output power at 1 dB gain compression and a 3.2 dB noise figure. RF ports are DC coupled enabling the user to customize system corner frequencies.

The TGA4830 is suitable for a variety of wideband electronic warfare (EW) systems such as radar warning receivers, electronic counter measures (ECM), decoys, jammers and phased array systems. It is also an excellent choice for 40 Gb/s NRZ applications. The TGA4830 is capable of driving an Electro-Absorptive optical Modulator (EAM) with electrical Non-Return to Zero (NRZ) data. In addition, the TGA4830 may also be used as a predriver or a receive gain block. The part is lead-free and RoHS compliant.
