10
+The FLL177ME is a Power GaAs FET that is specifically designed to provide high power at L-Band frequencies with gain, linearity and efficiency superior to that of silicon devices. The performance in multitone environments for Class AB operation make them ideally suited for base station applications. This device is assembled in hermetic metal/ceramic package.

+2, 4, 8 1.1 GHz Low Power Prescaler with Stand‐By Mode == MC12093
13
+
14
+A prescaler is an electronic circuit (or sometimes a counter/divider) that divides the frequency of an input signal by a fixed integer value before passing it on to the next stage.
15
+
16
+### 🔧 Key Idea
17
+
18
+If you feed in a high-frequency signal (say 1 GHz), and the prescaler is set to ÷10, the output will be 100 MHz.
19
+
20
+This makes it easier for slower digital circuits, timers, or microcontrollers to process signals that are otherwise too fast.
