DESCRIPTION The 20-watt RF MOSFET Amplifier Module for 12.5-volt mobile radios that operate in the to 941-MHz range. The battery can be connected directly to the drain of the enhancement-mode MOSFET transistors. Without the gate voltage (V GG=0V), only a small leakage current flows into the drain and the RF input signal attenuates to 60 dB. The output power and drain current increase as the gate voltage increases. With a gate voltage around 4V (minimum), output power and drain current increases substantially. The nominal output power becomes available at 4.5V (typical) and 5V (maximum). At VGG=5V, the typical gate current is 1 mA. This module is designed for non-linear FM modulation, but may also be used for linear modulation by setting the drain quiescent current with the gate voltage and controlling the output power with the input power. FEATURES Enhancement-Mode MOSFET Transistors (IDD VGG=5V, Pin=50mW Broadband Frequency Range: 896-902/ 935-941MHz Low-Power Control Current IGG=1mA (typ) at VGG=5V Module Size: x 9.88 mm Linear operation is possible by setting the quiescent drain current with the gate voltage and controlling the output power with the input power

With Multi-Touch in OS X, you can use realistic gestures like swiping or pinching to switch between apps, navigate your content and get the most out of your desktop space.

The new Force Touch trackpad takes all the capabilities of Multi-Touch and adds force sensors that detect subtle differences in the amount of downward pressure you apply. This lets you have a deeper connection to your content, bringing more functionality to your fingertip. It also introduces haptic feedback to MacBook Pro — allowing you to not just see what’s happening on the screen, but to feel it.
