The Telewave TPRD duplexers enable a transmitter and a receiver to operate simultaneously using a single antenna. These devices are engineered to minimize signal loss while also providing optimal isolation to prevent interference between the transmitting and receiving signals. Their Pass-Reject configuration incorporates a bandpass filter with an adjustable notch specifically tuned to the receiver's frequency, enhancing performance even when frequencies are closely spaced.
Telewave's high-quality construction of cavity duplexers ensures improved rejection of any unwanted transmitter signals, offering enhanced protection for the receiver. Both the selectivity and the insertion loss can be fine-tuned by rotating the precisely calibrated connector loops.
The cavities in Telewave duplexers are constructed from ¼-inch thick aluminum top plates, which are permanently welded to the aluminum outer conductor for durability. The use of silver-plated tuners, beryllium copper finger stock contactors, and Invar tuning rods with threads guarantees maximum stability under temperature fluctuations, a higher quality factor ("Q"), and reliable performance over many years.
