Transistors, & RF Power Amplifier Modules

XR-2212 The XR-2212 is an ultra-stable monolithic phase-locked
loop (PLL) system especially designed for commercial two-way and data communications and control system applications. Its on board reference and uncommitted operational amplifier, together with a typical temperature stability of better than 20ppm/�C, make it ideally suited for frequency synthesis, FM detection, and tracking filter applications.

Primary use is 16 channel, frequency control in many GE, & Ericsson DELTA, RANGR, PHOENIX and similar two-way radios.

2N7000 N-Channel Enhanced Mode Field Effect Transistors. These devices are used in many RASCAL GLX and GLK sound card interfaces, as they have been designed to minimize on-state resistance while providing rugged, reliable, and fast switching performance. They can be used in most applications requiring up to 400mA DC and can deliver pulsed currents up to 2A. These products are particularly suited for low voltage, low current applications. Because of their insulated gate feature, they also perform a measure of isolation between gate and source.

2/ .99, 2N7000

This transistor is used in some PSK31 circuits to activate transceiver PTT. Control of the PTT action is via software.
The same PTT feature is activated in SSTV/sound card software. 4 / .99 MPN2222

This device is designed as a general purpose amplifier and switch. The useful dynamic range extends to 100 mA as a switch and to 100 MHz as an amplifier. Employed in many PSK31 interfaces as the PTT switch.

The T200125 is used to construct 2kw, 3kw, and 5kw, 1:1 and 4:1 BALUNs ! The iron powder toroid material in the T-200-125 has a low value permeability of 10. This means, the lower permeability materials (iron powder or ferrite) can operate at higher flux density without saturation, thereby permitting higher RF power. The T-200-125 is almost impossible to saturate in amateur use.
