PGEN45 RF generator.

Generators is undoubtedly one of the most used elements of our practice. PGEN45 modules, which is based on a integrated circuit LTC1799 are linearly controlled rectangular signal generators ranging from 8 kHz to 45 MHz.

Generators is undoubtedly one of the most used elements of our practice. Is not always necessary to have a digitally controlled generator with many additional features. PGEN45 Modules are a simple compromise between parameters and price.

PGEN45 modules, which is based integrated circuit LTC1799 are linearly driven generators rectangular signal. With two potentiometers allow coarse and fine adjustment of the output frequency in the range of from about 8 kHz to 45 MHz. The output voltage is almost constant throughout the range of 5 Vpp.

Basic Features:
  • Precision square wave generator
  • Adjustable Output signal range: 8.3 kHz to 45.5 MHz
  • The frequency deviation is less than 1.5% (5 kHz to 20 MHz)
  • Temperature stability: ±40ppm/°C
  • Output: 5 VDC CMOS
  • Output impedance: 100 ohms
  • Output signal duty cycle is 50% (±1% at 1 kHz - 2 MHz, ±5% for 2 MHz - 20 MHz)
  • Supply voltage: 6-15 V DC

PGEN45 modules are simple and easy to use source CMOS signal levels of 5 Vpp. Foundation modules are resistor-programmable oscillators of Linear Technology LTC1799.

The main advantages of circuits LTC1799 is their high frequency stability (± 40ppm / ° C), 50% duty cycle output signal and CMOS output levels with an impedance of 100 Ohms. Integrated circuits are designed to generate a signal in the range of 1 kHz to 33 MHz and in the range of 5 kHz to 20 MHz, the frequency error is less than 1.5%.

In addition, the modules are equipped PGEN45 LDO regulator series LM3480IM3, providing a wide range of power supply voltage that can range from 6 to 15 V. The output voltage is 5 V regulator, which also defines the generator output voltage of 5 Vpp.

Application Generator:

PGEN45 modules are designed to generate a square wave in the range from about 8 kHz to 45 MHz. The power supply modules can be in the range of 6 to 15 V and the output signal level is 5 Vpp. The output frequency can be set using two potentiometers roughly and gently.

To use modules PGEN45 just connect the power supply voltage in the range of 6-15 V and the two potentiometers to set the desired output frequency.

Application:
  • Cheap precise oscillator
  • Generator for SDR receiver
  • Reference source for switching power supplies
  • Compensation crystal oscillator
  • Synchronization signal generator
