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, or in RF
attenuation circuits, in which case the PIN diode is utilized
as a continuously-variable RF resistance by controlling the
magnitude of the DC bias current through the diode.

Receiver Protection Limiter Diodes
Limiter Output
Skyworks’ series of silicon limiter diode chips provides
passive receiver protection over a wide range of
frequencies from 100 MHz to beyond 30 GHz. These
devices utilize Skyworks well established silicon technology
for high resistivity and tightly controlled thin basewidth
PIN limiter diodes. Limiter circuits employing these devices
perform with strong limiting action and low loss.
The receiver protector function is performed by a specially
processed PIN diode, known as a limiter diode. The PIN
limiter diode can be described as an incident-powercontrolled, 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.
The input power level at which the limiter diode’s
impedance starts to decrease in response to a large input
signal amplitude is primarily determined by the diode’s I
layer thickness. The diodes which “turn on” at the lowest
signal levels have the thinnest I layers.

Tuning Varactor Diodes
Features
• Large available change in capacitance for wide
bandwidth
• Low resistance for low loss
Skyworks series of select 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 and wide phase range variable phase shifters.
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.
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.

Schottky Diodes
Features
• Low capacitance for high frequency operation
• Excellent sensitivity
• High reverse breakdown voltage
Skyworks series of select silicon Schottky diodes are
optimized for use as detector and mixer diodes at
frequencies from below 10 MHz to higher than 20 GHz.
This family of products includes medium, low and zero
bias detector (ZBD) barrier height Schottky junctions with
low junction capacitance and low series resistance.
Schottky junctions are formed by depositing specific
metals on either n-type-doped silicon (low or medium
barrier height) or on p-type-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.
