RF attenuators
Several RF attenuators are needed at a site to ensure proper receive
adjustments. The attenuators are used at the LNA sites to offset the excess
gain from the Tower Top amplifiers, to balance the receive path, and to
attenuate the BMR signal path. Use the following specifications when
choosing vendors:
■ 1 dB increments
■ 0.5 dB accuracy or better
■ female N connector / male N connector
■ Specified frequency range
• 800 MHz systems – requires attenuator specification to include
806-821 MHz range
• 900 MHz systems – requires attenuator specification to include
896-901 MHz range
