The battery-powered mobile devices include portable navigation devices (PNDs) and GPS-enabled CDMA handsets.
The LNA module offers a lower profile and lower external component count than currently available competing solutions, best addressing the shrinking size requirements of present space-constrained mobile devices. The RF2815 also features an optimal combination of low noise-figure, high gain, high linearity and low power consumption – all critical performance attributes for battery-operated, GPS-enabled mobile devices.
The cellular- and PCS-band rejection characteristics of the integrated SAW filter equip the RF2815 for non-concurrent and simultaneous GPS (S-GPS) operation, both of which are implemented in GPS-enabled CDMA handsets.
‘We’re particularly excited about the launch of the RF2815,’ said Paul Augustine, general manager of RFMD’s Component Solutions Business Unit. ‘The majority of today’s CDMA handsets incorporate GPS functionality, and location-based services continue to gain in popularity in smart phones and in other mobile devices. The RF2815 is first in a line of innovative new products from RFMD that address this expanding market segment. It leverages our leadership in GaAs pHEMT and packaging technologies and signals our entry into surface acoustic wave filter integration in our front end products.’
Technical features of the RF2815 include:
Low noise-figure: 0.85 dB typical.
High gain: 13.5 dB.
High IIP3: +8 dBm.
CMOS-compatible shutdown mode.
Current consumption tunable via a single resistor.
No need for external DC-blocking capacitors.
ROHS Compliant.
