AY-J100 & AY-J101 PIN Diode Switch Assemblies

Aeroflex introduces a new series of high power PIN diode switch assemblies for use as antenna horizontal orvertical polarization for radio applications in the 2 GHz range, up to 20 GHz.

The switch assemblies are SPDTconfiguration and accepts a transceiver input, and connects one or two antenna outputs, eitherone at a time, orboth simultane-ously, with the desired switchable 90 degree phase off-sets.

RF SWITCH MODULE

Model BY-1923 RF Switch Module is a bi-directional, 12 port subassembly used to divide and/or attenuate an RFsignal from single port (labeled Radio port A), to or from anyof 11different ports. Sixof these ports (labeledPorts C, D, F, H, J) offer variable attenuation of
0 to 80 dB in 1dB increments. The other Five ports (labeled B,E, G, K, M) provide a fixed attenuation.

TWO CHANNEL & QUAD COMBINER

Models AY-FO4S and AY-FO5S combiners from Aeroflex / KDI-Integrated can combine four 70 W average power transmitter channels at any frequency in the band into a single antenna. The combiner, which operates over the full operating range of 851 MHz-866 MHz, makes it easier to configure transmitters and antennas in base station systems to increase capacity.

Designed for either CDMA or TDMA applications, the combiner features high isolation of 65 dB between transmitter channels and 55 dB minimum from the antenna port to any transmitter input port. Filtering is also included in the combiner to provide second harmonic rejection of at least 55 dB over the 1702 MHz-1732 MHz frequency range. Maximum insertion loss is 7 dB and dissipated power is internally absorbed and convection cooled with a large finned area. The combiner is designed to handle 300 W peak with 60 W CW reflected power from the antenna port. It is supplied with Type N connectors.

SUBSYSTEM / MANUFACTURING DESIGN

With in-house capabilities that include design and environmental testing, as well as manufacturing capabilities, Aeroflex / KDI-Integrated Products offers subassembly design and manufacturing services. A range of RF/microwave signal/processing components, plus embedded microprocessor firmware design, helps reduce the time it takes to create the subassemblies.

Switch matrices are common examples of subassemblies from Aeroflex / KDI that utilize the performance and multiple configurations of the SWX series of switches that allow the matrix to achieve a high level of isolation. A common use for a switch matrix subassembly is for testing antenna receiver paths in cellular and PCS base stations. Insertion loss of a 12-way matrix is typically 2 dB and the frequency range is 1.85-1.99 GHz. The maximum VSWR is 1.35 under all conditions and all circuit RF paths are matched within ½ dB of each other. The switches are internally terminated and will drop into the 50W termination in the "off" position.
