Introduction

The TRF37C75 is housed in a 2.00mm x 2.00mm ultra-thin small outline no-lead (WSON) package with a power-down pin, making this device ideal for applications where board space and low-power mode are critical. The TRF37C75 is designed for ease of use. For maximum flexibility, this product family operates from a common 5V supply with a current consumption of 85mA. In addition, this family incorporates an active bias circuit that provides a stable and predictable bias current over process, temperature, and voltage variations. To meet gain and linearity budgets, the device is designed to deliver a flat gain response and excellent OIP3 output up to 4000MHz. For space-constrained applications, this family is internally matched to 50Ω, simplifying implementation and minimizing the required PCB footprint. The device is a 5V general purpose RF gain block. It is a SiGe Darlington amplifier with integrated 50 Ω input and output matching. The device contains an active bias circuit to maintain performance over a wide temperature and voltage range. The included power down function allows the amplifier to shut down saving power when the amplifier is not needed. Fast shut down and start up enable the amplifier to be used in a host of time division duplex applications. The TRF37C75 is a fixed gain RF amplifier. It is internally matched to 50 Ω on both the input and output. It is a fully cascadable general purpose amplifier. The included active bias circuitry ensures the amplifier performance is optimized over the full operating temperature and voltage ranges.
