Maxim Integrated Products rolls out the MAX2664/MAX2665 low-noise amplifiers (LNAs) designed specifically for UHF and VHF mobile TV applications.

Available in a 0.86mm x 0.86mm, 0.4mm-pitch wafer-level package (WLP) with only four pins, they require one external component (an input-match inductor) to complete the board-level design, thus offering minimised solution footprint aimed at handheld designs.

Using Maxim's SiGe BiCMOS process, these compact broadband LNAs deliver 15dB of gain, support the 75MHz to 230MHz (MAX2665) and 470MHz to 860MHz (MAX2664) frequency ranges, and offer a low 1.1dB noise figure for improved receive sensitivity over discrete and CMOS solutions.

A low operating supply current of 3.5mA (typ) offers longer battery life in the end equipment. An integrated bypass switch places the LNAs in bypass mode (5µA, typ) during high-signal-level conditions to extend power savings and protect the LNAs.

The MAX2664/MAX2665 operate from a 2.4V to 3.5V supply, and are fully specified over the -40°C to +85°C extended industrial temperature range. Prices start at Rs.35.49 ($0.76) (1000-up, FOB USA). Evaluation kits are available for bench-level evaluation. Pricing for the EV kit is Rs.2,334.80 ($50) (each, FOB USA).
