PIN Diodes
Switching Applications
PIN diodes are some of the most widely used diodes in
the world and range in applications from RF switching
in satellite television receiver low noise block converters
(LNB), to automotive remote garage door openers,
to land mobile radio transceivers and cable television
automatic level controls.
The circuit below shows a pair of PIN diodes used to
form a single pole, double throw switch. In this switch, a
positive control current typically of the order of 10 mA is
applied to one of the bias inputs to place that side of the
switch into its low insertion loss state, while a negative
bias voltage is applied to the other bias input, forcing
the diode on that side of the switch into its maximum RF
impedance state to produce high isolation on that side of
the switch.
PIN diodes are three layer diodes, comprised of a heavily
doped anode (the “P” layer) and a heavily doped cathode
(the “N” layer) separated by a virtually undoped intrinsic
layer (the “I” layer). Under forward bias, charge carriers
from the P and the N layers are forced into the I layer,
which reduces its RF impedance. When a reverse bias
voltage is applied across the PIN diodes, all free charge
carriers are removed from the I layer, thereby causing its
RF impedance to increase. This variable RF impedance
versus DC, or low frequency bias signal, allows the diode
to be used in RF switching circuits in which the PIN
diode is either heavily forward-biased or reverse biased.
In RF attenuation circuits, the PIN diode is utilized as a
continuously-variable RF resistance by controlling the
magnitude of the DC bias current through the diode.

A resistive attenuator can be built utilizing one or more
PIN diodes. In this type of circuit, the RF resistance of the
PIN diode is adjusted to a desired value by varying the

Limiter Diodes
Output Power (dBm)
The PIN limiter diode can be described as an incident
power controlled, variable resistor. In the case when no
large input signal is present, the impedance of the limiter
diode is at its maximum, thereby producing minimum
insertion loss, typically less than 0.5 dB. The presence of a
large input signal temporarily forces the impedance of the
diode to a much lower value, producing an impedance
mismatch which reflects the majority of the input signal
power back towards its source.

Schottky Diodes
SMS7621-040LF Schottky Detector Diode
Schottky diodes are optimized for use in detector and
mixer applications at frequencies from below 10 MHz to
higher than 20 GHz. Skyworks’ family of products include
medium, low and zero bias detector (ZBD) barrier height
Schottky junctions with low junction capacitance and low
series resistance.
The SMS7621-040LF combines low capacitance
(nominally 0.2 pF) and low barrier height to produce a
detector diode with excellent sensitivity.
SMS7621-040LF
50 Ω
Schottky junctions are formed by depositing specific
metals on either n-doped silicon (low or medium barrier
height) or on p-doped silicon (ZBD barrier height). The
characteristics of the diode are determined by the type of
metal deposited on the semiconductor material, as well
as the type of dopant in the semiconductor layer, among
other parameters.

Tuning Varactor Diodes
RF
In
Skyworks series of silicon tuning varactor diodes are used
as the electrical tuning elements in voltage controlled
oscillators (VCOs), voltage variable analog phase shifters
and voltage tuned filters (VTFs). This family of diodes
includes abrupt junction tuning varactors, useful for low
loss, narrow band circuits, and hyperabrupt junction
varactors, useful for wide bandwidth VCOs and VTFs as
well as wide phase range variable phase shifters.
VCONTROL
V CONTROL
Phase Shifter Diagram
Tuning varactors are PN junction diodes. The depletion
region that forms at the junction of the diode acts as a
nearly-ideal insulator, which separates the highly-doped
anode from the cathode layer, thus forming a parallel
plate capacitor. The thickness of the depletion layer can be
increased by applying a reverse bias voltage to the diode.

Capacitance (pF)
The cathode layer’s doping profile is very carefully
designed to produce a tightly controlled capacitance
versus reverse bias voltage performance characteristic.
The cathode layer of an abrupt junction diode has
uniform dopant concentration throughout its thickness,
which results in a low series resistance and moderately
large change in capacitance versus bias voltage. By
contrast, the doping concentration of cathode layer of
hyperabrupt varactor diode is designed to change by
several orders of magnitude, typically over the depth of
a few microns. This non-constant dopant concentration
versus depth of the hyperabrupt diode’s cathode layer
produces a much larger available change in capacitance
versus reverse voltage, necessary for wide bandwidth or
phase shift range applications.
