MICRO LAMBDA YIG Filters, model types MLFP
Series and MLFR-series are available with integrated
analog driver circuits.
MICRO LAMBDA drivers eliminate the need for
customers to design or develop their own driver
circuits and sophisticated test and alignment procedures.
Integrating a driver at MICRO
LAMBDA’s factory ensures that peak performance
will be achieved at the time of manufacture.
Alignment and compensation with the particular
YIG filter can be maximized down to the component
level.
All drivers in this series provide input voltage
regulators, and compensation circuits to improve
frequency drift.
YIG drivers act as Voltage-To-Current convertors,
converting standard 0-10 Volts numbers into
mA of current to tune a magnetic tuning coil.
POSITIVE INPUT ANALOG DRIVERS
PA Series
MICRO LAMBDA positive analog drivers are
available for commercial environments. Standard
products provide 0-10 Volt tuning input and
operate over the 0° to 65° temperature range. |
|
The PA series of analog driver provide the main
coil current from the +15 volt input line. Current
increases linearly from 0 mA = 0 GHz at a rate of
approximately 50 mA per 1 GHz. A 2-8 GHz filter
will require 100 mA @ 2 GHz and 400 mA @ 8
GHz.
Negative input drives which provide the main coil
current on the –15 volt input line, are available as
an option.
Frequency drift performance can be optimized
with the inclusive temperature compensation circuits
within the driver. This yields filter/driver
combinations set at the factory with excellent frequency
accuracy performance.
In special cases, speed-up circuits like those
used to improve the tuning speed of YIG oscillators
can also be included to provide both fasttuned
filters and with good accuracy. Filter parameters
can be maximized during factory alignment
to meet customer specific requirements.
