PN Series: High Performance SMT Frequency Synthesizers Improve Air Traffic Alert Systems

The PN-1090 frequency synthesizer from EM Research was designed to enhance the performance of Mode Select (Mode S), Traffic Alert and Collision Avoidance (TCAS), and Air Traffic Control Radar Beacon Systems (ATCRBS). The unit utilizes internal frequency control logic capable of switching between the up and down-link frequencies of 1030 and 1090 MHz. The unit also features an internal reference, power output of +7 dBm, and low phase noise (<-95 dBc/Hz @ 10 KHz). The PN-1090 operates over the standard temperature range of -55°C to +85°C and is able to withstand high levels of vibration and shock. All PN synthesizers are housed in a small surface-mount package (0.9” x 0.9” x 0.15”).

Applications: Air traffic alert systems, mobile radios, point-to-point / multi-point radios, 2G and 3G Repeaters, wideband transceivers and other satcom and commercial wireless applications requiring a surface-mount part with high-rel capabilities.
