This VHF linear amplifier works for 50 MHz frequency using 2SC1946A with power output about 20 Watt. It needs input 30mW and output 25W for 150 Mhz. It seems can be used for 144 Mhz without modification. There are Power IC and 2SC1946A with low-pass filter on the board. Some Experiences I have checked Mitsubishi Catalogue and found it is 175 Mhz(ft), 3W input - output 30W(at 13.5Vcc), Gp10dB. I reffered Linear Amplifier Hand Book for deciding capacitors and coils. I made PCB with cutting by cutter knife and removing by heat with solder tool. After mounted all parts on the board, I tried ... Read Full Story

A few designs for remote control switches, using VG40T and VG40R remote control pair, are shown here. The miniature transmitter module shown in Fig. 1, which just measures 34 mm x 29 mm x 10 mm, can be used to operate all remote control receiver-cum-switch combinations described in this project. A compact 9-volt PP3 battery can be used with the transmitter. It can transmit signals up to 15 metres without any aerial. The operating frequency of the transmitter is 300 MHz. The following circuits, using VG40R remote control receiver module measuring 45 mm x 21 mm x 13 mm, can be used to: (a) ... Read Full Story

Video fans and professionals in the field will find in this small signal distributor-amplifier an excellent ally when it’s necessary to distribute a single video signal across several equipments. The circuit shown here should have a lot of applications. Basically, the distribution amplifier takes the composite video signal from a video player (VCR) or a video generator (analogue output) and buffers it in such a way that it can be simultaneously applied to up to five different video equipment inputs, like monitors, TV sets, other VCRs and so on. For example, in a hall, the image produced by a central DVD player can be ... Read Full Story
