Low Noise Oscillators
Mon, 01/27/2003 - 9:36am
For applications between 600 MHz and 2.5 GHz that require a low jitter sine wave signal, the M-tron M4001 or M4002 oscillator is ideal. The M4001/M4002 oscillator is packaged in a 9 × 14 mm J-lead ceramic package. The M4001 is a 3.3 volt device, and the M4002 is a 5 volt device. The M4001/M4002 is a low noise design oscillator that offers sub-picosecond jitter at .15 ps RMS typical (integrated from 12 kHz to 20 MHz off set from carrier). Stability is ± 100 ppm over operating temperature. The M4001/4002 also offers low phase noise ( 120 dBc/Hz at 10 kHz, 145 dBc at 100 kHz) and ± 50 ppm APR pull capability. With a wide modulation bandwidth of 500 kHz minimum, direct modulation of the M4001/M4002 is possible. The M4001/M4002 is well suited as an IF local oscillator, or mixer local oscillator driver for various 2.4 GHz spread spectrum transceiver chipsets, IQ modulators, mixers, and IEEE 802.11b (WLAN) ISM band applications.
