Pasternack Enterprises, Inc., a manufacturer of RF and microwave products, has released new RF isolaters and circulators for use in wireless infrastructures and distributed antenna systems. According to the company, the new ferrite circulators and isolators cover many of the common communications bands including UHF, AMS, Tetra, Cellular, PCS, UMTS and LTE frequencies.
Designed to protect RF components from excessive power reflection by acting as a unidirectional trap, isolating the signal so that any reflected energy at the load is trapped or dissipated, the new RF isolators from Pasternack are 2-port passive devices that operate between 380 MHz to 2.2 GHz. Pasternack’s RF isolators feature maximum power ratings to 1,000 Watts and up to 20 dB isolation depending on the desired configuration. SMA or Type-N connectors are included.
The new RF circulators (also referred to as RF duplexers) from Pasternack Enterprises are designed to control the signal direction and flow inside of an RF circuit. RF circulators are unidirectional and circulate the flow of energy from each port to its clockwise adjacent port. Like the RF isolators, the circulators are made of ferrite materials, which determine the direction that the entering signal will flow. Designed with SMA or Type-N connectors, the RF circulators operate between 380 MHz to 2.2 GHz and feature maximum power ratings to 1,000 Watts and up to 20 dB isolation.
