Tagore Technology Inc., a pioneer of high-power, low current GaN-based RF switches, announced the introduction of the TSL8329M, a dual-channel low noise amplifier (LNA) with integrated RF switch, multichip module. Designed for demanding applications, the module operates from 3.3 GHz to 4.2GHz. This dual-channel module is architected with cascading, two-stage LNA and a high-power GaN-based fail-safe RF switch. The TSL8329M is well-suited for 5G infrastructure and TDD massive MIMO system.

“With integrated dual-channel RF front end, the high performance TSL8329M is well suited for the most demanding 5G infrastructure radios, small cells and massive MIMO system. The footprint and pinouts allow easy adaption in complex MIMO configurations,” said Klaus Buehring, Tagore Technology’s chief marketing officer. 

The TSL8329M has NF of 1 dB with 32 dB of gain at 3.6 GHz with an output third-order intercept point (OIP3) of 35 dBm. In bypass mode, the LNA provides 13 dB of gain. In power-down mode, the device draws 5 mA. In transmit operation, when RF inputs are connected to a termination pin (TERM-CHA or TERM-CHB), the switch provides a low insertion loss of 0.45 dB at 3.6GHz and handles LTE average power (9 dB peak to average ratio) of 43 dBm for full lifetime operation. The device comes in a RoHS compliant, compact, 6 × 6 mm, 40-lead LFCSP.
