| Surface Mount Voltage Controlled Oscillator EGSM 920 - 960 MHz MLO80100-00940 V2.00 Features q q q q q LSM1 Package 4.0 0.8 IDENT 12.7 11.8 VCC RF 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 1.6 5.5 1.7 0.8 1.5 3 3.2 5.5 7.15 2 8.0 SOLDER RESIST 4 DETAIL A. 1 DETAIL A.

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 -20C to +70C. Devices will oscillate normally with tuning voltages from 0V to +10V. 3. Output power window includes unit to unit variation, temperature effects -20C to +70C 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. M/A-COM Ltd. North America: Tel.

Used in conjunction with a bypass capacitor this will yield improved power supply decoupling and noise suppression. Environmental Specification Devices are designed to operate over the temperature range of -20C to +70C and after exposure to the shock, vibration, thermal shock and moisture conditions typically encountered in base station and subscriber terminal environments.
