MAX2686/88: GPS LNAs provide low noise and save space with a WLP package
Maxim Integrated Products introduces the MAX2686/MAX2688, low-noise amplifiers (LNAs) designed for GPS-enabled applications operating in the 1575MHz band. Packaged in a 0.86mm x 0.86mm, 0.4mm-pitch wafer-level package (WLP) with only four pins, these LNAs minimize solution footprint for today’s continually shrinking handheld designs. Maxim’s advanced SiGe BiCMOS technology enables this space-saving design. Device specifications outperform GaAs and pHEMT LNAs and integrated RF CMOS receivers, and performance surpasses today’s larger competitive options. The MAX2686/MAX22688 only require two external components to complete the board-level design (plus an optional resistor for logic-enabled shutdown). These LNAs are ideal for GPS L1, Galileo, and GLONASS applications like cellular phones, portable navigational devices (PNDs), and module customers who want to improve GPS receive sensitivity.The
Pin-compatible versions are in development that offer variable levels of performance based on gain, current consumption, and linearity. An integrated LDO option will also be available to enable direct operation off of VBATT. Contact your local Maxim representative for more information.
The MAX2686/MAX2688 operate from a 1.6V to 3.3V supply, and are fully specified over the -40 degrees Celsius to +85 degrees Celsius extended temperature range. Prices start at $0.50 (1000-up, FOB USA). The MAX2686EVKIT and MAX2688EVKIT are also available for bench-level evaluation. Pricing for the EVKIT is $50.00 (each, FOB USA).
