3 Description

The TRF3302-Q1 is a high-gain, low-noise amplifier (LNA) designed for GNSS receiver applications. The device has 16.9dB power gain with an ultra-low noise figure of 0.85dB for high sensitivity GNSS receivers. An input-referred P1dB of –10.2dBm and IP3 of
–5.4dBm helps maintain the receiver sensitivity in the presence of jamming signals from cellular bands.

The broadband design of TRF3302-Q1 supports a wide array of bands in GNSS satellite constellations such as GPS, Galileo, BeiDou, QZSS, NavIC/IRNSS, and GLONASS. The device also supports L-band of Iridium satellite system. A 2-element (capacitor and inductor) input match provides low noise and good return loss performance for L1 (GPS), E1 (Galileo), and B1 (BeiDou) bands. The inductor value is adjustable to achieve nearly 150MHz of bandwidth with minimal performance degradation for applications that need coverage for lower GPS bands L2 through L5, Galileo E6 through E5a, BeiDou B3 through B2a, QZSS L6, NavIC L5, and GLONASS bands G2 through G3. A 4-element external input matching network combined with the wideband output of TRF3302-Q1 delivers performance coverage for all major GNSS bands with a ≅ 1.2dB NF, and S11 and S22 better than –10dB.

The TRF3302-Q1 operates on a 1.8V to 3.3V single supply and consumes only 4.6mA of current for power and thermal sensitive designs. The device features a digital logic compatible enable pin for additional power savings. The TRF3302-Q1 is rated for an operating ambient temperature of –40°C to +125°C.
