Description

The MLO81100-01850 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 high linearity 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 automatic 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 typical supply voltage with
reduced performance.

5. For typical phase noise at other offsets see phase noise curve.

6. Defined as (1900 - 1800) / (VT1900 - VT1800) MHz/V.

7. Non harmonic spurious less than -70dBc.

1. Exceeding these limits may cause permanent damage.

2. A series resistor will allow operation at any greater supply voltage.
Used in conjunction with a bypass capacitor this will yield
improved power supply decoupling and noise suppression.

3. Static sensitive, observe appropriate precautions.
