The TSL8329M from Tagore Technology is a Dual-Channel, Integrated Front-End Module that operates from 2.0 to 4.2 GHz. It has a cascading, two-stage Low Noise Amplifier (LNA) and a GaN based SPDT switch. In high gain mode, the cascaded two-stage LNA and switch have noise figure of 1 dB and provide gain of 32 dB at 3.6 GHz. In low gain mode, one stage of the two-stage LNA is in bypassed, providing 13 dB of gain at a lower current of 45 mA. In transmit operation, when RF inputs are connected to a termination pin, the switch has an insertion loss of 0.45 dB at 3.6 GHz.
The TSL8329M requires a DC supply of +5.0 V and consumes 5 mA of current during power-down mode. It is available in a surface-mount package that measures 6.00 x 6.00 x 0.85 mm and is ideal for SDARS, 4G/5G infrastructure radios, small cells, cellular repeaters, and phased-array radar applications.
