... RF5111 Theory of Operation and Application Information The RF5111 is a three-stage device with 28 dB gain at full power. Therefore, the drive required to fully saturate the output is +5dBm. Based upon HBT (Heterojunction Bipolar Transistor) technology, the part requires only a single positive 3V supply to operate to full specification. Power control is provided through a single pin interface, with a separate Power Down control pin. ...

... High current conditions are potentially dangerous to any RF device. High currents lead to high channel temperatures and may force early failures. The RF5111 includes temperature compensation circuits in the bias network to stabilize the RF transistors, thus limiting the current through the amplifier and protecting the devices from damage. The same mechanism works to com- pensate the currents due to ambient temperature variations ...

... Pulse Generator Notes about testing the RF5111 The test setup shown above includes two attenuators. The 3dB pad at the input is to minimize the effects that the switching of the input impedance of the PA has on the signal generator. When V change can cause the signal generator to vary its output signal, either in output level or in frequency. Instead of an attenuator an isolator may also be used ...

... RF5111 PCB Solder Mask Pattern Liquid Photo-Imageable (LPI) solder mask is recommended. The solder mask footprint will match what is shown for the PCB metal land pattern with a 2mil to 3mil expansion to accommodate solder mask registration clearance around all pads. The center-grounding pad shall also have a solder mask clearance. Expansion of the pads to create solder mask clearance can be provided in the master data or requested from the PCB fabrication supplier ...
