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.
