HMC-C200 v04.1109 DIELECTRIC RESONATOR OSCILLATOR MODULE, 8.0 - 8.3 GHz Features Tuning Frequency: 8.0 - 8.3 GHz Low SSB Phase Noise: -122 dBc/Hz @ 10 kHz Offset Single Positive Supply: +6 to +15V @ 116 mA Internal Voltage Regulator Internal Buffer Amplifier High Output Power: +14.5 dBm Typical Applications The HMC-C200 DRO Module is ideal for: • Test & Measurement Equipment • Lab Instrumentation • Industrial / Medical Equipment -40°C to + 85°C Operating Temperature General Description The HMC-C200 is a high performance dielectric resonator oscillator (DRO) that incorporates Hittite’s ultra-low phase noise technology and provides -122 dBc/Hz SSB phase noise at 10 kHz offset. The output buffer also provides 14.5 dBm of output power. Internal temperature compensation allows this DRO to operate over a temperature range of -40°C to + 85°C with a frequency drift of only 2ppm/°C. The Vtune port accepts an analog tuning voltage from +7 to +12V and provides a range of ±1 MHz from the center frequency. The DRO is packaged in a small, moisture sealed 1.5”x1.5” (36 x 36 mm) module with a field replaceable SMA Connector. The HMC-C200 can be used as a drop-in module if the SMA connector is not used. 3 DIELECTRIC RESONATOR OSCILLATOR • Military, EW, ECM & Communications Functional Diagram Electrical Specifi cations, TA = +25° C, Frequency = 8.2 GHz, VDC = +6.5V Parameter Frequency Range Frequency Accuracy Power Output, Center Frequency SSB Phase Noise @ 1 kHz Offset, Center Frequency SSB Phase Noise @ 10 kHz Offset, Center Frequency SSB Phase Noise @ 100 kHz Offset, Center Frequency SSB Phase Noise @ 1 MHz Offset, Center Frequency Tune Voltage (VT) Electric Tuning Range 2nd Harmonic (2Fo) 3rd Harmonic (3Fo) 7 -117 12 Min. 8.0 Typ. 8.2 ±250 13.5 -95 -122 -140 -150 9 ±1 -28 -35 12 Max. 8.3 Units GHz kHz dBm dBc/Hz dBc/Hz dBc/Hz dBc/Hz V MHz dBc dBc 3-4 F or price, delivery, and to place orders, please contact Hittite Microwave Corporation: 20 Alpha Road Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order Online at www.hittite.com HMC-C200 v03.1009 DIELECTRIC RESONATOR OSCILLATOR MODULE, 8.0 - 8.3 GHz Electrical Specifi cations (Continued) Parameter Frequency Pushing Frequency Pulling (into 2.0:1 VSWR) Output Return Loss Frequency Drift Rate (Temperature) Voltage Supply (VDC) Supply Current @ VDC = +6.5V Frequency Drift vs. Time @ 25°C 6 116 1 Min.

(This is initially set at the factory per customer specified frequency, See Application Notes herein) Ordering Instructions Each HMC-C200 DRO requires tuning to a specific frequency in the 8.0 - 8.3 GHz range. To order an HMC-C200, this frequency must be specified at the time of purchase. Hittite guarantees a ±250 kHz range around this specified frequency upon delivery. Please refer to the Application Notes for more details. For example, when ordering an HMC-C200 centered at 8.200 GHz, specify HMC-C200-8200. 3-6 F or price, delivery, and to place orders, please contact Hittite Microwave Corporation: 20 Alpha Road Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order Online at www.hittite.com HMC-C200 v03.1009 DIELECTRIC RESONATOR OSCILLATOR MODULE, 8.0 - 8.3 GHz Outline Drawing 3 DIELECTRIC RESONATOR OSCILLATOR 3-7 NOTES: 1.

A mechanical tuning screw (MT) is provided that can adjust the center frequency by approximately ±20 MHz from the factory setting. This screw is set at factory per customer specified frequency. Adjusting the screw clockwise increases the frequency while turning the screw counterclockwise decreases the frequency. The mechanical tuning screw (MT) has stops at either end of its approximately 8 turn range. Do not attempt to force screw the past stops. 2. Connect the RF output to a Spectrum Analyzer and adjust the mechanical tuner (MT) to set the output frequency to within 1 MHz of the desired value. 3. Set Spectrum Analyzer settings for a 10 MHz span centered on the desired output frequency. Change the Reference Value of the Spectrum Analyzer to be approximately 15 dBm and change the vertical scale to be 1dB / division such that the peak oscillation frequency is visible on the screen. 4. Use the tune voltage (VT) to maximize the DRO output power and note the frequency. Note: The tune voltage should never be adjusted higher than +15V. 5. If the frequency is meeting the new requirement and the output power is greater than 12 dBm, then the tuning procedure is complete. If the frequency is not meeting the requirement then carefully readjust the mechanical tuner (MT) and tune voltage (VT) until the output frequency is within the required range. 3 DIELECTRIC RESONATOR OSCILLATOR Please Note: 1. The tune voltage (VT) sustains oscillation over a fairly narrow range (approximately 1 MHz) before output power, temperature stability and phase noise performance starts to degrade. In some cases it is possible for the tune voltage (VT) to be adjusted to the point where oscillation stops. Therefore, the mechanical tuning screw (MT) should be used as a coarse tune and the tune voltage (VT) is effectively a fine tune. In PLL applications where the tune voltage (VT) is used within the loop, this limited voltage range must be considered during the design of the loop. A limiting circuit must be used to keep the VT voltage within the optimal range. 2. If the output power is less than 12 dBm then the DRO may be at the correct frequency but the phase noise performance and the stability over temperature may both have been degraded. It is therefore recommended that the customer verify phase noise and stability after custom tuning. 3-8 F or price, delivery, and to place orders, please contact Hittite Microwave Corporation: 20 Alpha Road Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order Online at www.hittite.com HMC-C200 v03.1009 DIELECTRIC RESONATOR OSCILLATOR MODULE, 8.0 - 8.3 GHz Fixed Output Frequency Application 3 Phase Locked Application F or price, delivery, and to place orders, please contact Hittite Microwave Corporation: 20 Alpha Road Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order Online at www.hittite.com 3-9 DIELECTRIC RESONATOR OSCILLATOR
