GPS RF FRONT END OVERVIEW
The NuWaves GPS RF Front End is a highly efficient, high transmit/receive gain module to boost
performance of data links. This high-performance RF front end is a powerful combination of the NuPower
13G05A RF power amplifier, low noise amplifiers, a high isolation diplexer between the transmit and
receive paths with rejection of GPS L1 band, and band-reject filters.
This module accepts a nominal 0 dBm (1 mW) RF input and provides 45 dB of transmit gain from 1626.5
to 1675 MHz and provides 47 dB of receive gain from 1518 to 1559 MHz. With a typical isolation of 80dB
between 1518-1559 MHz and 1626.5-1675 MHz bands, the NuWaves GPS RF Front End enables full duplex
operation. It supports both constant envelope and complex waveforms such as APSK, QAM, DVB-T, etc.
