A Control Circuit For Diode-based RF Circuits

We are willing to offer the technology to design a Driver circuit for stepwise temperature invariant performance of diode-based RF circuits such as p-i-n and Schottky diode-based attenuator, phase shifter, linearizer etc.

Sector: Electrical & Electronics
Country: India
Area of Application:
• Electronically controlled RF attenuators for various RF/Microwave instruments.
• Electronically controlled RF phase shifters for RF/Microwave instrument and digital beam forming networks.
• Gain control of RF/Microwave amplifiers for on-board and ground based instrument.
• RF Linearisers for TWTAs, SSPAs
Keywords: Control Circuit, Diode, RF
Advantages:
• The driver circuit will provide bias to the RF diodes to provide temperature compensated RF performance without using any temperature sensors.
• No temperature sensor is required, since properties of the diodes themselves are used to achieve the temperature compensation performance.
• The temperature controlled bias voltage/current generated according to the junction temperature of the RF diodes themselves, thus any temperature gradient will not affect the temperature compensation.
• Temperature changes induced by RF energy dissipated within the diodes are also compensated.
• No trial and error method is involved to optimize the circuit performance
