CA911F2V10

TWIN DIPLEXER 3GSM850-GSM900

Kaelus rack mounted filter assemblies provide the ability to install commonly used filter configurations into a 19" rack making installation easy and minimising rack space requirements. The CA911 combines part band 3GSM850 and part band GSM900 technologies into a single feeder in a simple twin package.

FEATURES

  • Combines TX/RX of GSM900 and 3GSM850 BTS to one feeder
  • Provides rejection of GSM900 frequencies for 3GSM850 downlink
  • Main and diversity filters
  • Provides rejection of 3GSM850 frequencies for GSM900 uplink
  • Low Passive IM performance
  • 19" rack mounted, front or rear mounting

electrical
Impedance 50ohms
Insertion loss 2dB maximum (TX + RX band edge), 1dB typical (TX + RX mid-band)
1.2dB maximum across passband (variation)
Return loss 17dB minimum
Group delay variation <200 ns
Maximum input power GSM900 = 120W (average) / 500W (PEP) e.g. 4 x 30W GSM carriers
3GSM850 = 120W WCDMA (with 10dB crest factor)
Intermodulation products <-155dBc for two tones at any frequency in either TX band at 20W CW each
TX passband = <-97dBc for two tones at any frequency in either TX band at 20W CW each
Isolation – 3GSM850 to GSM900 band 40dB minimum
3GSM850 Tx error vector magnitude (main & diversity) < 7.5% (on a carrier with centre frequency in the range 882.2 - 887.2MHz), 6% typical at 25ºC
GSM Rx group delay variation (main & diversity) < 200 ns
