Ceramic Resonator Bandpass Filter 50Ω CSBP-D1228+ 1203 to 1253 MHz The Big Deal • Excellent Rejection 1010 MHz, 1450 MHz: 30 dB typ. 920 MHz, 1600 MHz: 50 dB typ. • Low Passband Insertion Loss: 0.9 dB typ. • Stable IL vs. Temperature: ±0.3 dB typ. CASE STYLE: KS1509 Product Overview The Mini-Circuits CSBP-D1228+ is a ceramic-coaxial-resonator based bandpass filter offering outstanding close-in rejections low insertion loss and high power handling for use in transmitter and receiver RF chains. Key Features Feature Advantages High Selectivity The CSBP-D1228+ filter incorporates High-Q custom ceramic resonators that enable sharp rejection near the passband while maintaining 4% passband bandwidth. Low Passband VSWR: 1.4:1 typ. The CSBP-D1228+ 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 in-band frequency ripple. RF Power Handling: 16.5W Tested at high level RF powers, the CSBP-D1228+ can withstand high power CW signals within the passband making this filter ideal for higher power transmitters. Temperature Stability: ±0.3dB The use of highly stable materials enables the CSBP-D1228+ to maintain minimal insertion loss variation over a wide temperature range over the passband and the stopband. Rugged construction The CSBP-D1228+ has been qualified over a wide range of thermal, mechanical and environmental conditions including withstanding the stress of extensive solder reflow cycles. Small size: 0.88" x 0.625 x 0.225" The use of high dielectric constant resonators enables the CSBP-D1228+ to support a large number of poles in a small footprint enabling high selectivity in a small surface mount design.
