3 Description

The TRF3302 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 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 delivers performance coverage for all

major GNSS bands with a ≅ 1.2dB NF, and S11 and

S22 better than –10dB.

The TRF3302 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 is rated for an operating

junction temperature of –40°C to +125°C.
