  • One Relay for Multiple Supply Voltages
    current to a value that is approximately two thirds of its initial value. The duty cycle of the PWM is automatically controlled independent of coil parameters like inductance and resistance, or even the supply voltage. With this type of circuit a 6-V relay can be operated from a wide voltage range
  • Phase Locked Loop Systems Design for Wireless Infrastructure Applications
    Base stations use phase locked loop (PLL) systems to generate either RF or IF local signals to up-convert. baseband signals to RF signals or vice versa. There are different ways of integrating PLL system blocks,. including voltage-controlled oscillators (VCO), based on system requirements
  • Schottky Mixer Feature High Dynamic Range
    The voltage controlled oscillator (VCO) and the mixer represent two key components in a wireless communications system. For many applications, the local oscillator (LO) drive of a mixer is provided by a VCO. Often, the VCO output is amplified and then filtered before being presented to the LO
