MAX2667/69: Boost GPS receiver performance with ultra-low-noise-figure amplifiers

The MAX2667/MAX2669 provide different linearity options to suit system requirements. For customers who wish to ensure a higher level of receive performance in the presence of signal blockers, the MAX2669 (at 4.5dBm) provides approximately 8dBm better in-band and out-of-band IIP3 than the MAX2667 (at -3.5dBm), for a mere 4.0mA extra supply current.

For power efficiency, customers can expect longer battery life in their end-equipment design thanks to the MAX2667, which is optimized for a low operating supply current of 4mA (typ). When not in use, both LNAs have an optional logic-enabled shutdown mode that reduces supply current to less than 1microamp.

These LNAs are offered in a space-saving, 0.4mm-pitch wafer-level package (WLP) that takes up a mere 1mm2 of board space, much less than the competition. Only requiring four external components to complete the board-level design (plus an optional resistor for logic-enabled shutdown), the MAX2667/MAX2669 enable the smallest solution footprint for today's handheld designs.

The MAX2667/MAX2669 operate from a 1.6V to 3.3V supply. Fully specified over the -40 degrees Celsius to +85 degrees Celsius extended temperature range, they are available in an ultra-small, 0.86mm x 1.26mm, 6-pin WLP. Prices start at $0.54 (1000-up, FOB USA). The MAX2667EVKIT and MAX2669EVKIT are also available for bench-level evaluation. Pricing for the EV kits is $110.00 (each, FOB USA).
