0.7mm² UHF/VHF LNA ICs enable mobile phones with DTV feature

Maxim has launched low foot-print ultra and very high frequency receiving low noise amplifiers, which can work with only one external component i.e. inductor. MAX2664/MAX2665 low-noise amplifiers (LNAs) are made for designing UHF and VHF mobile TV receiving phones and other such mobile devices. Measuring 0.86mm x 0.86mm, 0.4mm-pitch wafer-level package (WLP) with only four pins 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. Feature low operating supply current of 3.5mA (typ). 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.
Price: Each $0.76 (1000-up, FOB USA). Evaluation kits are priced at $50.00 (each, FOB USA).
