• Supply voltage +3.3Vdc to +5Vdc
• 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)

• 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 -90dBc over

the spectrum of 100kHz to 1GHz.
