Basic Tier Traps

QBR Band Reject Tiering Filters

testQBR.pngPPC takes insertion loss and return loss seriously. Poor return loss can affect modem performance. QoS® Series QBR filters have an industry leading minimum return loss of -16 dB (typically -20 dB). QBR filters also have an insertion loss of -0.5 dB (typically -0.2 dB) which reduces the need to install costly drop amps. Drop cable, connectors splitters and ground blocks all have a -16 dB return loss. Why shouldn’t your filters too?
