Low-power, low-noise amplifier for GNSS IoT applications
This discrete LNA is optimized to operate from 1559 to 1606 MHz, has a very low current (1 mA @ 1.8 V supply) and single power supply (1.5 to 3.6V range) for design flexibility and simplicity. The device’s broad frequency range covers GPS L1, GLONASS, Galileo and Compass navigation systems and it minimizes external components thereby reducing the bill of materials for OEMs. The SKY65623-682LF comes in an extremely compact form factor (5L QFN 0.8 x 0.8 mm package), for low-power Internet of Things (IoT) devices.
Specifications include;
– Small signal gain: 16.5 dB typical
– Noise figure: 0.85 dB typical
– Out-of-band IIP3: –11.5 dBm typical
– Current consumption: 1 mA typical
– Shutdown current: 0.1 μA typical
– Output impedance internally matched to 50 Ohms
– Single external input matching inductor
– Single DC supply: 1.5 to 3.6V
– Minimal number of external components required
– Small QFN (5-pin, 0.8 × 0.8 mm) package (MSL1, 260C per JEDEC J-STD-020)
