Description
The MLO81100-01700 is a fundamental single ended
oscillator designed for use in cost sensitive wireless and
telemetry applications. The device has been optimised by
careful selection of the bipolar transistor and varactor diode
for low phase noise and highly linear tuning characteristics.

The low profile surface mount package used provides for
electrical shielding, ease of assembly and repeatable
performance. M/A-COM’s surface mount manufacturing
techniques together with automated assembly and electrical
testing ensure a high degree of electrical and mechanical
repeatability at low cost and in high volume. Manufacturing
is carried out in an ISO 9000 qualified facility.

1. All specifications apply with a 50 ohm load impedance.
2. Tuning voltages shown are the minimum and maximum voltages required to tune the frequency range including temperature effects -20°C to
+70°C. Devices will oscillate normally with tuning voltages from 0V to +10V.
3. Output power window includes unit to unit variation, temperature effects -20°C to +70°C and frequency flatness (typically ±0.5 dB at any
constant temperature).
4. Devices may be operated at lower supply voltage with reduced performance.
5. For typical phase noise at other offsets see phase noise curve.
6. No non harmonic spurious visible when measured on a test system with a dynamic range of 70 dB.
This Preliminary Data Sheet Contains Typical Electrical Specifications Which May Change Prior To Final Introduction.
