Model #MDR5100-20000 Phase Locked Oscillator Features • • • • • Frequency: 20 GHz Low Phase Noise: -105 dBc/Hz @ 100 kHz Low Spurious: -80 dBc Typical Internal Reference Design Environmental Screening Available Description API Technologies’ Series MDR5100 Phase Locked Oscillators use a Dielectric Resonator in the resonant circuit. The circuit is lightly loaded to obtain the lowest phase noise possible. The resonator is epoxied to a printed circuit board and well grounded to minimize modulation sidebands during shock and vibration. Buffer amplifiers are used to provide isolation from load VSWRs; Regulators filter noise on the DC input voltage. External reference models are also available. A lock indicator circuit is provided to signal an out-of-lock condition Specifications¹ TYPICAL Ta = +25°C 20 CHARACTERISTIC Frequency (GHz)² Mechanical Tuning Bandwidth (MHz)³ Output Power (dBm) Variation Over Temperature (dBm) Spurious (dBc) VSWR +/- 20 +/- 20 Min. +13 +12 +/- 0.75 +/- 1 -80 -70 +/- 10ppm max - Frequency vs. Temperature Stability Phase Noise (dB)⁴ MIN/MAX Ta = -20°C to +50°C 20 -90 dBc/Hz @ 1 KHz -100 dBc/Hz@ 10 KHz -105 dBc/Hz @ 100 KHz -120 dBc/Hz @ 1 MHz 1.5 2.0 -20 -15 TTL (High=Locked) TTL (Low=Locked) +12 300 +12 310 Harmonics (dBc) Lock Indicator Supply Power DC mA Phase Voltage Set to (nom.)

Specifications labeled “min.” or “max.” are guaranteed in a 50 Ohm system over the specified temperature range. 2. Output frequency must be specified, and it is an integer multiple of the internal crystal reference frequency. 3. Mechanical tuning of PLO in unlocked mode. 4. Phase Noise at offsets <100 kHz is dependent on external reference and can be approximated as follows: Phase Noise (dB) = 20log(N) +3 dB above the external reference phase noise, where N = multiple of reference. 5. Actual or impending loss of lock. Rev Date: 3/11/2016 © API Technologies Corp. Proprietary Information Page # 2 | www.apitech.com | micro.apitech.com | +1.888.553.7531 | [email protected]
