API DDF11M Pin diode driver Datasheet

PIN Diode Drivers
Spectrum Microwave o ffers a complete line-up of PIN diode switch
drivers with output current capability of 10 mA to 50 mA and
switching speeds as fast as 6 ns. Thin film metalization on ceramic
substrates ensures low parasitic capacitance for fast switching, small
size, and excellent reliability. AH FMt drivers are designed by our
experienced engineering staff; thus, if the drivers listed in the
table below do not meet your requirements, we would be happy
to discuss a custom circuit to fit your exact needs.

NOTES:
1. Output current is measured into a 10 Ohm load to ground.
2. Load is a 50 pF (39 + 10 scope probe) capacitor in parallel with a grounded cathode HP5082-0C01 PIN diode.
Ton is measured from 50% of input (from a S<ASOO gate) to 10 +1 V diode load.
Toff is measured from 50% of input to the rated open ckt negative voltage across diode load.
3. Exclusive of current supplied to the load.
4. To avoid exceeding power rating, the max. Vee should be held to 5 V when driving grounded anode diode.
5. De-rate linearity to 175 º C. Temperature is measured at case bottom, which should be heat sunk if necessary.

High Speed Drivers
A universal PIN diode driver with excellent noise
immunity, very fast switching, 100 mA current
spikes and available test points for increasing
quiescent output current.
1. W hen using inverting input, connect bias pin 5 to
non-inverting input pin 6.
2. W hen using non-inverting input, connect bias pin 5
to inverting input pin 4.
3. For -30 mA output current, connect pin 8 to pin 9.
4. For positive output currents other than 15 mA or
30 mA , an external resistor can be connected
between pin 8 and +5V . See graph.
5. The negative output current varies with V ee and is
specified at -12V . W hen driving grounded anode
diodes, V ee should be kept at -5V where the negative
current will be 5 mA . It may be increased by connecting
a resistor from TP- (pin 14) to V ee (pin 1). See figure.

Dual High Current Driver
Two independent universal medium speed (100 ns)
drivers with separate positive and negative quiescent
output current programming and separate
input logic mode control. This driver is often
used in SPDT applications by driving both inputs
from the same TTL input signal and applying
opposite logic inputs to the two mode controls.
1. Inputs are inverting when M ode control has a logic
high input.
2. Inputs are non-invertin g when M ode control has a
logic low input.
3. To increase positive output current from the normal
+30 mA to +50 mA , connect +50 mA pin to +5 V .
4. To increase negative output current from the normal
–30 mA to –50 mA , connect –50 mA pin to V ee.
5. The negative output current does not vary with \/ee,
which should not exceed –5 V when driving
grounded anode diodes to avoid high power
dissip ation in the drivers.

APPLICATION NOTES
PIN Diode Sw itching Times
Heat Sinking
PIN diodes are used as RF switches because of their
low off-capacitance/on-resistance product. However,
they store a significant charge during conduction that
must be removed before they will turn off. Typically,
this is specified as storage time (TS), which is made to
look better than it might be by rating it with a high ratio
of reverse (IR) to forward (IF) current. W hen switching
these diodes with a non-spiking driver, the typical TS
will be multiplied by the specified ratio. For example,
the M A 47120 has a TS of 12 ns with IF=20 mA and IR=
200 mA . W ith symmetrical currents as delivered by
high current drivers, the TS becomes 120 ns. High
speed drivers supply a spike of several hundred mA at
turn-on and turn-off to shorten the TS of the PIN diode.
The power dissipated in PIN diode switches is conducted
to the bottom of the package. The thin walls leading to
the top of the package represent a high thermal resistance.
The total power in the hybrid is the sum of it own current
drain multiplied by the voltage of each supply plus the output
current of each driver multiplied by the supply voltage less
the V F of the PIN diode.
The total can be substantial especially in the multiple
high current drivers. If your calculations show that the
hybrid should be heat sunk, you may find it convenient
to place it top down on the PC board so that the bottom
of the hybrid may be mounted directly to the metal
case of your package.
Other Diode Drivers
In addition to these standard circuits, Spectrum Microwave produces a wide range of custom-designed drivers. These include a dual
ECL-input driver (DD212) and a 28-channel 50 mA driver (DD2850). Spectrum Microwave is also one of the largest custom hybrid
manufacturers in the United States. Please contact the factory or your local representative for a quote on your driver requirements or
your own custom hybrid circuit.
