Maxim MAX2664/MAX2665 low-noise amplifier range

Maxim has released the MAX2664/MAX2665 low-noise amplifiers designed specifically for UHF and VHF mobile TV applications.

The devices offer a fully integrated LNA solution in a 0.86 x 0.86 mm, 0.4 mm-pitch, wafer-level package with only four pins. They require one external component (an input-match inductor) to complete the board-level design.

The company’s SiGe BiCMOS process enables these compact broadband LNAs to surpass the performance of today's larger options. They deliver 15 dB of gain, support the 75 to 230 MHz (MAX2665) and 470 to 860 MHz (MAX2664) frequency ranges and offer a low 1.1 dB noise figure for improved receive sensitivity over discrete and CMOS solutions.

In addition, users can expect longer battery life in their end equipment due to an operating supply current of 3.5 mA (typ).

An integrated bypass switch places the LNAs in bypass mode (5 µA, typ) during high-signal-level conditions to extend power savings and protect the LNAs.

The devices operate from a 2.4 to 3.5 V supply and are fully specified over the -40 to +85°C extended industrial temperature range.
