Cisco Indoor/Outdoor Active GPS Antenna (GPS-ACT-ANTM-SMA)
Specifications
Figure 1 Specifications for the Cisco GPS-ACT-ANTM-SMA Antenna
Specification Description
Maximum RF input power 1 W
Power Supply 3-5VDC,
20mA typical @3V
30mA typical @5V
Amplifier Gain 27dB typical @25C
Amplifier Filter Topology Antenna-LNA1-BPF1-LNA2-cable-SMA(m)
connector.
Due to a topology without front end filter
immediately following the antenna, antenna has
the benefit of lower noise figure, but may not be
suitable for collocation with a high power wireless
transceiver.
Connector SMA male
VSWR
1
1. VSWR = voltage standing wave ratio.
2:1 or less
Noise Figure 1.5dB typical @25C
Amplifier Filter Topology Antenna-LNA1-BPF1-LNA2-cable-SMA(m)
