Q-Tech SINE WAVE User Manual
Q-TECH
COR PORATI ON
Description
The Q-Tech Sine Wave Sources encompasses state-of-the-art
sinewave source with low harmonic distortion and a precise
sinewave output.
A flexible design allows Q-Tech Corporation to offer a
variety of choices of output power and load. Based on this
flexibility, Q-Tech welcomes specifications with parameters
other than standard. An external trimming capacitor option
is available for applications that require a tight frequency
stability.
The AT-Cut crystal utilized in the design allows for high
stability for a particular temperature range extending from
-55ºC to +125ºC. For more information, please refer to the
stability vs. temperature on the following page.
The reliable construction of these sinewave oscillators
qualifies them for more stringent environmental
applications. Military screening per MIL-PRF-55310, Level
B is available as an option.

Other Design and Test Options
Sine Wave options are available with a Q-Tech
MCM part number:
• Supply voltage +5Vdc to +18Vdc
• Output power -10dBm to +13dBm into 50Ω
(see note 1)
• Harmonics better than -20dBc (see note 2)
• Sub-harmonics better than -30dBc (see note 3)
• Amplitude stability versus temperature to
within ±1% (see note 4)
• VCXO Sine Output (see details in VCXO data
sheets)
• Phase Noise and Jitter built to specification
including static and vibration.
• Low supply current
• QCI tests
• Tight frequency stability versus temperature,
supply voltage, and load variations
• Low g-sensitivity and low phase noise
• Low spurious (see note 5)
• Low Harmonic Distortion (THD < 5%)
• Low frequency aging, Allan Variance
• High-shock resistant
Notes:
1. The output level is determined by the supply
voltage, load, and package size.
2. A specified harmonic level of -20dBc is easily
achievable. The typical harmonics of Q-Tech Sine
Wave source are better than -25dBc.
3. Sub-harmonic level is determined by frequency
multiplication method, supply voltage, output
power, and input current.
4. Typical amplitude stability over temperature is
±10% or less.
5. Typical spurious level is better than -60dBc over the
spectrum of 100kHz to 1GHz.
(*) Frequencies less than 500Hz require an external 1µF AC coupling capacitor at the output pin.
(**) Higher frequencies are available with a Q-Tech custom part number.
