MGA-81563 0.1–6 GHz dBm Amplifier Data Sheet Description Avago’s MGA-81563 is an economical, easy-to-use GaAs MMIC amplifier that offers excellent power and low noise figure for applications from 0 GHz. Packaged in an ultra-miniature SOT-363 package, it requires half the board space of a SOT-143 package. The output of the amplifier is matched to 50Ω (better than 2.1:1 VSWR) across the entire bandwidth. The input is partially matched to 50Ω (better than 2.5:1 VSWR) below 4 GHz and fully matched ...

MGA-81563 Applications Information Introduction This high performance GaAs MMIC amplifier was d eveloped for commercial wireless applications from 100 MHz to 6 GHz. The MGA-81563 runs on only 3 volts and typically requires only deliver 14.8 dBm of output power gain compression. An innovative internal bias circuit regulates the device’s internal current to enable the MGA-81563 to operate over a wide temperature range with a single, positive power ...

Standard statistics tables or calculations provide the prob- ability of a parameter falling between any two values, usually symmetrically located about the mean. Referring to Figure 12 for example, the probability of a parameter being between ±1σ is 68.3%; between ±2σ is 95.4%; and between ±3σ is 99.7%. 68% 95% 99% -3σ -2σ -1σ Mean (µ) +1σ +2σ +3σ (typical) Parameter Value Figure 12. Normal Distribution. RF Layout The RF layout in Figure 13 is suggested as a starting point for microstripline designs using the MGA-81563 amplifier. Adequate grounding is needed ...

The power supply is bypassed to ground with capacitor C3 to keep RF off of the DC lines and to prevent gain dips or peaks in the response of the amplifier. An additional bypass capacitor, C4, may be added to the bias line near the V connection to eliminate unwanted d feedback through bias lines that could cause oscillation. C4 will not normally be needed unless several stages are cascaded using a common power supply. When multiple bypass capacitors are used, consideration should be given to potential resonances. It ...

A second method illustrated in Figure 21b use for- ward-biased diodes in series with the power supply. For example, three silicon diodes connected in series will drop a 5-volt supply to approximately 3 volts. The use of the series diode approach has the advantage of less dependency on current variation in the amplifiers since the forward voltage drop of a diode is somewhat current independent. Reverse breakdown diodes (e.g., Zener diodes) could also be used as in Figure 21c. However, care should be taken to ensure that the noise generated by diodes in either Ze- ner or reverse breakdown is adequately filtered (e.g., by- passed to ground) such that the diode’s noise is not added to the amplifier’s signal.
