SLX-series surface mount frequency synthesizers from EM RESEARCH feature fixed-frequency or serially-programmable outputs in bands from 100 MHz to 3 GHz. Bandwidths are available from octave at fc >= 600 MHz to 20% bandwidths at 2.5 GHz. Customer-specified step sizes range from 10 KHz to 1 MHz. At 1 GHz frequency output, typical phase noise characteristics are 㫲 dBc/Hz at 10 KHz and 𤩣 dBc/Hz at 100 KHz offsets; at 3 GHz frequency output, phase noise is 㫭 dBc/Hz at 10 KHz and 𤩞 dBc/Hz at 100 KHz offsets. Typical supply is +3 VDC at <15 mA. Packaged in a 0.50 inches square surface-mount housing, the synthesizer is suited for use as local oscillators for up and downconverters in handheld and other wireless communications systems where small size is important.
