What does a PIN diode do?
A PIN diode behaves as a current-controlled resistor at radio and microwave frequencies. Like the conventional PN diode, it allows current flow in one direction when forward biased, but not in the other when it is reverse biased.
What is an RF limiter?
Pasternack RF limiters are broadband passive devices used for receiver and component protection and are also used for power leveling applications. RF limiters have power leveling limit thresholds of +9 dBm and have input power maximums to 1W CW.
What is the work of a Zener diode?
A Zener diode is a silicon semiconductor device that permits current to flow in either a forward or reverse direction. The diode consists of a special, heavily doped p-n junction, designed to conduct in the reverse direction when a certain specified voltage is reached.
What kind of diodes are used in pin limiters?
GC4700 Series The GC4700 series ceramic packaged diodes are specially processed PIN diodes designed for use in passive or active limiters at frequencies through Ku band. Thirteen categories of devices are offered for flexibility in design of low, medium and high power limiters.
Which is gml4700 series pin limiter diodes?
GML4700 Series The GML4701-GM1 is specifically designed for high volume surface mount applications. The GigaMite design is optimized for improved electrical and thermal performance over standard plastic package technology.
When does a PIN diode behave like a resistor?
Thus a PIN diode is essentially a DC-controlled high-frequency resistor. Just as important, if no DC current is present, the diode behaves like an open circuit. The frequency at which the PIN diode transitions from acting like a diode to acting like a resistor is a function of the thickness of the I-region.
What are the different types of Microsemi pin limiters?
Thirteen categories of devices are offered for flexibility in design of low, medium and high power limiters. Low VB limiters have thinner I regions for faster turn-on time and better flat leakage. Microsemi also manufactures “gold doped” limiters for fastest turn on time.
