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 pro鏗乴e surface mount package used provides for
electrical shielding, ease of assembly and repeatable
performance. M/A-COM鈥檚 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 quali鏗乪d facility.

1. All speci鏗乧ations 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擄C to +70擄C. Devices will oscillate normally with tuning voltages
from 0V to +10V.
3. Output power window includes unit to unit variation, temperature
effects -20擄C to +70擄C and frequency 鏗俛tness (typically 0.5 dB at
any constant temperature).
Speci鏗乧ations Subject to Change Without Notice.
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.
