Description
This Mini Line Amplifier 20dB Regulated Pass DC (MLA20RPDC) is an active one input, one outputamplifier optimized for GPS applications. This equipment accepts signals covering all major GNSS
constellations with excellent gain flatness and a low L1 noise figure. In the standard configuration, theJ1 port accepts DC voltage from a connected GPS receiver. This voltage is regulated and used topower the internal amplifiers while unregulated voltage is passed through the antenna port to power aconnected active antenna or other upstream devices.

Use Cases• As an in-line amplifier to negate the insertion loss of a long cable run.
• To add amplification to a signal provided by a passive antenna.
• As an amplifier in a re-radiating system.
• In combination with one of our splitter devices to create a GPS distribution network.
• When an amplifier is needed but the LA20RPDC has too large of a form factor.
