Description
The Polaris Gain Equalizer series is a negative slope equalizer that decreases attenuation linearly with frequency. This product family is used to compensate for the gain slope characteristics in communication equipment using broadband amplifiers such as L-band RF systems and wideband gateways.
Features
● Two types of negative gain equalizers
Surface mountable PCB (L x W x T): .59”[15 mm] x .47”[12 mm] x .02”[0.5 mm]
Housing with SMA connectors (L x W x H): 1.30”[33 mm] x .79”[20 mm] x .80”[20.3 mm]
● Excellent performance
Frequency range: 950 MHz to 2,150 MHz
Slope linearity: ±0.5 dB (typ.), ±0.75 dB (max.)
VSWR: 1.5 : 1 (typ.), 1.67 : 1 (max.)
Insertion loss at max. frequency: 1.0 dB (typ.), 1.75 dB (max.)
Slope compensation range: 1 to 10 dB
● Affordable price
Applications
● L-band amplifiers
● L-band converters
● Wideband routers and gateways
● Multi-band cellular phone signal repeaters
● DAS(Distributed Antenna Systems)
● RF transceiver modules
