Components
RF Connectors
HD-BNC™ is the newest line of small form
factor RF connectors designed to support rap-
idly growing demand for high bandwidth, high
reliability interconnection in the broadcast
and telecommunications industries. The high-
density BNC series (HD-BNC) is based on the
familiar quarter-turn BNC coupling connec-
tor pioneered by Amphenol in the late 1940s,
but with patented design advancements that
permit a four-fold reduction in footprint and
more than 20 percent reduction in weight while
maintaining true 75 ohm performance and the
robust mechanical properties expected from a
BNC interface. The Amphenol HD-BNC was
developed in close collaboration with leading
industry equipment makers and system integra-
tors to address the most common issues with
conventional high density solutions including
interface robustness and signal loss related to
long cable runs.

Cavity Bandpass Filter
The model Wifi2437-6A is a ruggedized, weath-
erproof cavity bandpass filter for outdoor WiFi
installations that has excellent rejection, han-
dles up to 40 W of RF input power and is ex-
tremely selective. The Wifi2437-6A has a center
frequency of 2437 MHz and a bandwidth of
more than 30
MHz (2427 to
2447 MHz),
along with maxi-
mum insertion
loss of less than
2 dB and pass-
band ripple of
less than 0.2 dB.
The filter has re-
jection of at least 60 dB at 2412 and 2462 MHz
and return loss of more than 18 dB. The unit
measures 108 × 56 × 29 mm and uses SMA fe-
male connectors. The Wifi2437-6A is rugge-
dized and weatherproofed for use in outdoor
environments, and has an operating tempera-
ture range of -40° to +70°C.

with a center frequency of 42 GHz. With a 3 dB
bandwidth of 1000 MHz minimum, the
insertion loss at center frequency is 1.5 dB.
Rejection at 40
GHz is greater
than 50 dB and
the VSWR is
1.5:1. This com-
pact filter de-
sign has an overall size of 1.20" × 0.5" × 0.5".
This model is supplied with 2.4 mm connectors.

Surface-mount Fixed Attenuators
This new wide-
band surface-
mount fixed at-
tenuator is
optimized for
performance
from DC to 20
GHz. Utilizing
EMC’s 40 plus years of experience in refining
attenuation solutions, the TS09 offers the best
performance to date for high frequency applica-
tions in an SMT package. These devices have
been noted for their excellent performance and
small size, measuring only 0.070" × 0.060" (1.78
× 1.62 mm). The TS09 wideband fixed attenua-
tor handles 200 mW of input power and is avail-
able in dB values from 0 to 10 dB in 1 dB incre-
ments.

Broadband Resistive Couplers
IMS announced the expansion of its line of low
loss broadband resistive couplers to include
wire bondable
terminals and
alternate config-
urations. The
IMK Series cou-
plers now come
in both forward
and reverse fac-
ing directions,
coupling values from 6 to 30 dB and are rated at
1 W dissipated power and 5 W through power.
The IMK Series resistive couplers are compact
(0.120" × 0.120") alternatives to more complex
narrow band couplers. They have been charac-
terized to 20 GHz and can exhibit insertion loss
less than 1 dB loss for nominal values greater
than 18 dB.

Three-way Power Dividers
Marki Micro-
wave an-
nounced the re-
lease of a new
line of broad-
band three-way
power dividers.
These power di-
viders are constructed using a unique design
approach that enables industry leading isolation
and amplitude/phase balance. The three-way
power divider line launches with two models:
the 0.4 to 12 GHz PD3-0R412 and the 0.6 to 16
GHz PD3-0R616. Custom designs are also
available. Contact the factory for more informa-
tion.

+12 to +33 dBm Limiter
The Mini-Circuits VLM-63-2W+ is a +12 to +33
dBm limiter that operates in a frequency range
from 30 to 6000 MHz. This limiter features low
insertion loss, 0.4 dB typical. The limiters
offer fast recov-
ery time, 5 nsec
typical; excellent
VSWR, 1.05:1
typical; and low
leakage power,
11.5 dBm typi-
cal. Applications
include: protects
low noise amplifiers and other devices from ESD
or input power damage and military, hi-rel ap-
plications. This limiter is RoHS compliant in ac-
cordance with EU Directive (2002/95/EC).
Price: $51.95 (1-9).

SP6T Switch
The SEM163
SP6T electro-
mechanical
switch is de-
signed for oper-
ation from DC
