TRF37C75IDSGR

The TRF37C75 from Texas Instruments is a high-performance RF Gain Block Amplifier designed for a wide frequency range of 40 MHz to 4000 MHz. This amplifier provides a typical gain of 18 dB and a low noise figure of 3.5 dB, making it suitable for various RF applications.

Key electrical characteristics include a typical output P1dB of 18 dBm and an OIP3 of 34 dBm at 2 GHz. The device operates with a supply voltage range of 4.5 V to 5.25 V and consumes a typical current of 85 mA, with a power consumption of 0.425 W. It features an output enable function and operates within an ambient temperature range of -40°C to 85°C.

The TRF37C75 is housed in an 8-WSON (2x2 mm) exposed pad package, designed for surface mounting. This compact package is ideal for space-constrained applications. The amplifier is internally matched to 50 Ohms, simplifying design and minimizing PCB area. It also includes a power-down mode for power-critical applications and offers robust ESD protection.

This RF gain block amplifier is suitable for applications requiring stable performance over temperature and voltage variations due to its active bias circuit. Its flat gain response and excellent OIP3 performance up to 4000 MHz make it a versatile component for RF front-end modules, wireless connectivity, and other RF systems.
