Description

The MLO80100-00940 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
anyconstant temperature).

Specifications Subject to Change Without Notice.

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.

1. Exceeding these limits may cause permanent damage.

2. A series resitor 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.

Envir onmental Specification

Devices are designed to operate over the temperature
range of -20°C to +70°C and after exposure to the shock,
vibration, thermal shock and moisture conditions
typically encountered in base station and subscriber
terminal environments.
