CDMA and GPS Preamplifiers
Best Combination of Performance, Packaging and Price
We provide very high-performance, low-noise, inline amplifiers for difficult
GPS and CDMA signal environments. The Glna and Clna Series of amplifiers are specifically designed for operation
at the frequencies used by our GPS and CDMA receivers, and their packaging and power consumption are optimized
to work with our products. They are a cost-effective way to make a significant improvement
in the reliability of your signal reception and offer the best combination of performance, packaging and price
on the market.
- Improves signal reception.
- Easy to install.
- Allows for extended cable lengths.
- Compact, weatherproof package.
Weak Signal Strength Environments
Many GPS installations require a very long cable between a rooftop-mounted GPS antenna and the receiver.
In these situations a low-noise, inline GPS amplifier can
make the crucial difference between your equipment operating properly or not. In many situations,
multiple preamplifiers are needed and the wide supply voltage range and extremely low current consumption
of our preamplifiers allows them to be cascaded over as long as 1000 feet using small diameter RG-59 type cable.
In other situations, using CDMA in place of GPS is the preferred signal option. Co-location facilities
are examples of such situations. These facilities are often isolated from the outside world
through layers of closed doors and solid walls with no windows. They present
very challenging signal environments and the use of a CDMA amplifier can make the crucial
difference. The very low noise figure of our preamplifiers is critical to receiving such weak signals.

High Interference Environments
Interference rejection is crucial in both GPS and CDMA receiver applications.
GPS antennas are often installed on rooftops with other communications antennas that are
radiating interfering signals. CDMA receivers must be designed to handle very
high dynamic range interference because of the fact that mobile phones transmit in a band
that is very close to the receive band, thus creating possible interference.
The Glna and Clna Series preamplifiers use surface acoustic wave (SAW) filters and highly linear
semiconductors to achieve very high interference rejection, even in the presence of high
levels of interference.

or the Clna (CDMA) Series Low Noise Amplifers datasheet.
