K&L has developed a series of reduced-size
lowpass clean-up filters with cut-off
frequencies as low as 460 kHz handling up
to 3.0 kW CW. Several innovations minimize
dissipated power. Part 3LL10-0.46/XQ0.70-
N/N, measuring 12.3”L x 3.5”W x 2.1”H, features 0.5 dB insertion loss
DC to 460 kHz and 60 dB rejection at 700 kHz, handling 3 kW input power.
A 4.5”L x 1.9”W x 1.25”H package passes to 100 MHz, rejects at 140
MHz, and handles 1.1 kW CW power.
BSC has independently developed a
fully reconfigurable adaptive filter bank
solution, designed for fast and seamless
switching to any of 256 filter states across
the 2-18 GHz range.
The BSC design facilitates a step change
in EW front-end preselection (or protection),
adding complete flexibility by producing
any combination of bandpass and band-stop
states almost instantly (<100 ns).
Suitable for fast-jet, naval and ground-based
environments, the robust customized
architecture is not limited to the 2–18 GHz
range or equal channel widths. More specific
solutions may be offered at VHF/UHF or
Dow-Key® has over
70 years of expertise
in designing and
RF switches and
specializes in custom and rugged
switching products for mission-critical
applications. Latest innovations include
an L-Band, non-blocking fan-out/
fan-in solid state network for a mobile
SATCOM station. The custom system
is a dual 4x48/48x4 switch matrix in a
ruggedized chassis with sub-modules
providing exceptional RF performance.
The design features a minimum of
60 dB isolation and a noise figure of
18 dB/20 dB. The control module is
equipped with a Windows-based PC
and removable and replaceable duplex
power supply cartridges. The system
may be controlled via LCD touchscreen
and Ethernet with SNMP v1 protocol.
Pole/Zero introduces new voltage-tuned filters (VTF) with center frequency
ranges extending up to 20 GHz for EW and Radar applications. The VTFs meet
extremely fast tuning requirements of under 150 ns with high selectivity, low
loss and power handling up to +10 dBm
in bandpass and notch configurations.
These Rx-oriented filters complement
Pole/Zero’s existing high power Tx
tunable bandpass and notch offerings
for EW environments.
