The TPRD-1444C and 1444CMproduce high performance in acompact design for the 135-151MHz VHF band. These duplexers areonly one-third of the size of earliermodels, and deliver equivalentperformance.

The TPRD-1444C/CM produces 70dB isolation at 600 KHz, with a 350watt power rating, and insertionloss is 1.5 dB or less. Each duplexerfits a standard 19" rack, with rackheight of 5.25" and 4" respectively.The TPRD-1444CM is suppliedwith adjustable mounting tabs forinstallation in a cabinet.

The TPRD-1444C/CM produces 70dB isolation at 600 KHz, with a 350watt power rating, and insertionloss is 1.5 dB or less. Each duplexerfits a standard 19” rack, with rackheight of 5.25” and 4” respectively.The TPRD-1444CM is suppliedwith adjustable mounting tabs forinstallation in a cabinet.

The TPRD-1446C offers highperformance in a compact designfor the 135-151 MHz VHF band.These duplexers are only one-thirdof the size of earlier models, anddeliver equivalent performance.

Custom-extruded 4" cavities allowhorizontal rack mounting. Threepass-reject sections for the transmitand receive paths provide 80 dBisolation at 500 KHz, with a 350watt power rating, and insertionloss of 2.5 dB or less. The duplexerfits a standard 19" rack, with rackheight of 8.75".

Telewave models TPRD-1584 andTPRD-1586 allow simultaneousoperation of a transmitter andreceiver into a common antenna.These Pass-Reject duplexers are anideal choice for systems requiringmaximum isolation, with closefrequency spacing down to 300KHz.

The TPRD-1584 has two, and theTPRD-1586 has three Pass-Rejectcavities each in the transmitter andreceiver sections. Selectivity andinsertion loss may be adjusted byrotating the calibrated connectorloops.

Telewave duplexers have 1/4-inchaluminum top plates which arefully welded to the aluminum outerconductor.As a result of their superiorconstruction, Telewave 8” cavityduplexers achieve greater rejectionof transmitter noise and spuriousradiation, providing excellentreceiver protection.

Silver-plated tuners, berylliumcopper finger stock contactors,and threaded Invar rods assuremaximum temperature stability,higher "Q", and many years oftrouble-free operation.

The Telewave TPRD-1566 allowssimultaneous operation of atransmitter and receiver into acommon antenna. This pass/rejectduplexer has low insertion loss,and is ideal for systems with closefrequency separation.

The TPRD-1566 has three pass/reject cavities in both the transmitterand receiver sections. This duplexeris designed for transmitters andreceivers with frequency spacingof 300 KHz or more. Selectivity andinsertion loss may be adjusted byrotating the calibrated connectorloops.

Because of their super i o rconstruction, these Telewave 6"cavity duplexers achieve greaterrejection of transmitter noiseand spurious radiation, providingexcellent receiver protection.

Telewave duplexers have 1/4"aluminum top plates which arefully welded to the aluminum outerconductor. Silver-plated tuners,beryllium copper finger stockcontactors and threaded Invarrods assure maximum temperaturestability, higher "Q", and many yearsof trouble free operation.

All duplexers are tuned andtested with customer-specifiedfrequencies prior to shipping. Iffrequency changes are required, thepositive locking mechanism allowsfor easy field tuning by rotating thethreaded Invar rod.

The optional TBC-40 indoor cabinetcompletely encloses the duplexer,and protects it from dust, dirtand tampering. All connectionsare accessible from the top of thecabinet.
