1) Waveguide Product Group Develops 2 New Components |
Renaissance Electronics has recently designed two new high
power waveguide products outlined below.
A. High power absorptive filter
This new design covers 2.7 to 2.9 GHz S-Band in WR284 waveguide and is
capable of handling power levels up to 1 MW Peak power and 3 KW average. It
has extremely high harmonic suppression with over 55 dB attenuation in the
2nd harmonic band.
The advantage of this design over a reactive filter is that it avoids
refracting the harmonic power back into the transmitter thus enhancing the
lifetime of the RF Source. This design is used for air traffic control radar
applications.
B. High Power Ferrite Junction Circulator
This novel design uses thin ferrite resonators to enhance the average power
levels and still maintain a compact size. This design operates over 2.7 to
2.9 GHz and is capable of handling over 50 KW Peak power and 3 KW average.
The design also avoids non-linear losses by suppressing the excitation of
spinwaves inside the ferrite material. Typical performances for this family
of circulators realize VSWR 1.15:1, isolation of 20 dB, and loss of 0.25 dB
per transit.
The advantage of this design is the compact size of only 6" x 7" x 3" for
high power handling. It is used in air traffic control radar systems.

F18 Radar Isolator |
|
Renaissance Electronics
recently received a follow-on low rate production order from a major prime
contractor to supply a unique 5-in-1 Isolator package. This special
configuration provides a very small footprint but contains 5 individual
isolators.
Renaissance Electronics initially developed this packaged Isolator set in
late 2004 and was qualified in early 2005. The unit will be used in a new
radar for the Navy’s F18 E/F series.

3) Switch Matrices Development Order for Aerial Common Sensor (ACS) |
Renaissance Electronics has been
chosen to develop a Narrow band UHF Switch Assembly that will be
utilized in the Aerial Common Sensor (ACS) Airborne Platform
Subsystem for the U.S. Army. Initial delivery of this system is
expected in November 2005 for this multi-year agreement.

4) RF Subsystem Wins New Military Power Divider Order |
|
Renaissance Electronics has been
awarded a new development project by a US based defense prime
contractor to design and manufacture two different models of
broadband 16-way dividers. The Divider’s are part of a larger
GPS System being developed by the prime. These dividers have low
insertion loss, high isolation and both cover over an octave in
bandwidth. There unique design yields compact size, given their
number of ports. These units also display good amplitude and
phase balance.

5) MTT-S Long Beach, California |
Renaissance Electronics would like to thank everyone that stopped by
our booth at this year's IMS symposium in Long Beach. Along with
meeting with existing customers, The Renaissance Electronics Show
Team was able to discuss several new development projects with new
customers.
We look forward to seeing everyone at MTT-S San Francisco next year! |
