AVT2776 A

The construction of a linear amplifier in. Part. It is not easy to power a few watts. Transistor circuits require the use of appropriate semiconductors and very careful adjustment of operating parameters. Although until now companies producing electronic components have not developed appropriate, integrated RF power amplifiers, affordable systems for DSL devices have appeared on the market. Their presence inspired them to build structures that use them for the lower KF bands. The presented kit was designed based on such a "cube". Relatively simple system, depending on the power supply can provide up to 18 W of power.

The device is especially recommended for amateur radio enthusiasts who want to increase the power of their transceivers

Selected parameters:

• the design uses the EL1503 chip
• 50 ohm input impedance
• output power 6.5 W (for +/- 5V and input voltage 1.2 Vpp)
• 18 W output power (for +/- 12V and 2 Vpp input voltage)
• very low level of harmonic content
• power supply - +/- 5 - +/- 12) V
• printed circuit board and documentation included
