Product Index
These small RF test aids are built in the FLEXI-BOX, which is a small aluminium screened RF enclosure. They can be assembled by you or supplied ready built and tested by us.
Bias Tee
Allows a DC supply current to be fed to the inner of a coaxial cable
for remotely powered equipment.
Broadband
Amplifier 1 GHz
This amplifier was designed as a quick solution for standing wave
measurements. It has turned out to be a most useful piece of equipment.
FLEXI-BOX KIT 63.5
mm long x 50 mm wide x 25 mm deep
The FLEXI-BOX is now available with blank photo-resist coated PCB's in the
original size only.
HF
Amplifier
This amplifier is designed to cover the HF band with the optimum
performance. It also covers the LF and MF bands and could be most useful
to radio hams.
Remotely
Powered VHF Pre-Amplifier
Designed as a general purpose VHF amplifier. Could be used for
a VHF radio installation and especially suitable for installation in
'remote' positions.
RF
Bridge
The RF Bridge is a directional device for splitting the forward and
reverse components in a transmission line.
RF Trap
The RF Trap is mainly intended for use in the measurement of small
harmonics in the presence of a large fundamental using a spectrum
analyser. It is particularly useful in digital communication systems such
as GSM, DCS, UAIS and WCDMA, where transmit harmonic spurs have to be kept
very small. It can also be used for other tests including mixer
measurements, where conversion efficiency can be measured with the mirror
image filtered out.
RF
Trap With Attenuators
The RF Trap With Attenuators is used for the same measurements as
the RF Trap above. The inclusion of attenuators, reduces the overall test
system cost and results in a simple, electrically reversible unit that
cannot produce a serious mismatch. It could be very useful in a production
environment or in the laboratory.
Stub
Filter
The stub filter can be used for the same tests with a spectrum
analyzer as the RF Trap above. It is a 'high frequency' measurement aid
(1.0 GHz +) and it is therefore advisable to use N or SMA type connectors.
BNC are available if they fit your requirements.
Termination
Box
This is intended to be a test aid and is also part of our Standing
Wave Demonstration Kit. It's description gives an opportunity to observe
the effects of series inductance in a resistor.
FLEXI-BOX
Transmission Line 63.5 mm long x 50 mm wide x 25 mm deep
The transmission line has a PCB with a 50 Ohm track running end to end.
This is intended to be used to build surface mount circuitry by using a scalpel and a soldering iron to achieve the required layout .
It is currently available in just the original size.
6
dB Splitter
This is a resistive splitter which gives good phase matching and low
amplitude ripple to 3 GHz using standard 0805 resistors.
VHF
Pre-Amplifier
Designed as a test aid but equally suitable for a VHF radio
installation.
Voltage/Current
Detector
Measures voltage and current in a coaxial cable from 0.3 MHz to 300 MHz. A unique and most useful product.
