Product Overview
The Mini-Circuits CSBP-A940+ is a ceramic-coaxial-resonator based bandpass filter offering outstanding close-in
rejection, low insertion loss and high power handling for use in GSM, cellular bands.
Key Features
Feature
Advantages
High Selectivity
The CSBP-A940+ filter incorporates High-Q custom ceramic resonators that enable sharp
rejection near the passband while maintaining 13% passband bandwidth.
Low Passband VSWR: 1.3:1 typ.
The CSBP-A940+ filter maintains typical VSWR over a wide passband frequency range making
this filter easier to integrate into receiver and transmitter RF chains with less concerns for inband frequency ripple.
RF Power Handling: 12.6W
Tested at high level RF powers, the CSBP-A940+ can withstand high power CW signals within
the passband making this filter ideal for higher power transmitters.
Temperature Stability: ±0.25dB
The use of highly stable materials enables the CSBP-A940+ to maintain minimal insertion loss
variation over a wide temperature range over the passband and stopband.
Rugged construction
The CSBP-A940+ has been qualified over a wide range of thermal, mechanical and
environmental conditions including withstanding the stress of extensive solder reflow cycles.
Small size: 1.04" x 0.55 x 0.225"
The use of high dielectric constant resonators enables the CSBP-A940+ to support a large
number of poles in a small footprint enabling high selectivity in a small surface mount design.
