The TSL8029N from Tagore Technology is a Front-End Receiver Module that operates from 2 to 5 GHz. This single-channel front-end integrates a cascaded 2-stage low noise amplifier (LNA) and a GaN-based SPDT switch. In high gain mode, the cascaded 2-stage LNA and switch provide a gain of 33 dB with a noise figure of 1.4 dB. In low gain mode, it switches one stage of the LNA to bypass mode and provides a gain of 14 dB. In transmit operation, when RF inputs are connected to a termination pin (TX), the switch provides an insertion loss of 0.5 dB at 3.6 GHz. It requires a DC supply of 5 V, and consumes 45 mA of current in low gain mode, and 90 mA of current in high gain mode. In power-down mode, the LNAs are turned off and the device draws 5 mA.
The TSL8029N is available in a surface-mount package that measures 5 x 5 mm and is ideal for SDARS, 4G/5G infrastructure radios, macro base stations, small cells, cellular repeaters, and phased array radar applications.
