The TRF37A73 is packaged in a 2.00mm × 2.00mm WSON with a power down pin feature making it ideal for applications where space and low power modes are critical.

The TRF37A73 is designed for ease of use. For maximum flexibility, this family of parts uses a common 3.3 V supply and consumes 55 mA. In addition, this family was designed with an active bias circuit that provides a stable and predictable bias current over process, temperature and voltage variations. For gain and linearity budgets the device was designed to provide a flat gain response and excellent OIP3 out to 6000 MHz. For space constrained applications, this family is internally matched to 50 Ω, which simplifies ease of use and minimizes needed PCB area.

For all available packages, see the orderable addendum at the end of the datasheet.

TIDA-00347 — Low Frequency RF Amplifier Reference Design

Wideband RF amplifiers require external coupling capacitors and an RF choke to supply bias to the output transistor collector.  As the frequency of operation is reduced, the choice of these components must be modified to maintain proper gain and linearity in the device.  This design (...)
