Buffer
Amplifier to Extract IF Signal Sample and Other Purposes
|
Z10000B Buffer Amplifier.
The Z10000B was developed to obtain an isolated signal sample from the IF of a
transceiver or receiver to output to a spectrum analyzer or panadapter. It's
available in a general purpose wideband version or a version optimized for the
Elecraft K2 transceiver.

Receiving
Filters
|
Z10010 Bandpass Filter.
Originally developed to use between an IF output and a panadapter, the Z10010 is
also usable anytime a narrow band (bandwidth between 5% and 2.5% of center
frequency) is required. Stock designs are available for the K2's IF (4915 KHz),
the K3's IF (8215 KHz), 9.00 MHz, 10.7 MHz, 28.1 MHz and 518 KHz. Other
custom frequencies are also possible.

 |
|
|
Z10020
Band Reject Filter. Developed to solve AM broadcast interference problems,
the Z10020 filter suppresses the AM medium wave band (540 KHz - 1690 KHz) whilst
passing frequencies below and above the medium wave broadcast band. The filter
is available with many options including connectors and weatherproof or indoor
enclosures.
|
 |
|
|
Z10022A High Pass
Filter. Designed as a lower price solution to AM broadcast interference
than the Z10020A. The Z10022A passes frequencies above 1800 KHz and
suppresses frequencies below this. The filter is available as an assembled
printed circuit board for installation in the purchaser's enclosure or as a
complete unit in a die cast enclosure.
|
 |
|
|
Z10023A
Elliptic High Pass FilterThe Z10023A is an
elliptic (Cauer) filter designed to simultaneously provide good signal
rejection at 1700 KHz and below, whilst providing minimum loss at 1800 KHz
and above.
|
 |
|
|
|
Z10024 Low Pass Filter.
Designed for longwave listening enthusiasts, the Z10024A
is a low pass filter that will suppress signals above the cutoff point. The
Z10024A is designed and built to meet customer's requirements, and it has
been supplied to customers with cutoff frequencies of 50 KHz, 140 KHz, 479
KHz, 520 and 880 KHz.

Low Noise, Medium Gain
(Norton) Amplifiers
|
Z10040B Norton Amplifier.
A high performance broadband, low noise preamplifier. 3 dB bandwidth extends
from below 100 KHz to above 40 MHz, and IP3 is in the +40 dBm range.
Design features permit indoor or outdoor mounting with direct DC power or
duplex DC power over the coaxial feed line.
|
 |
|
|
|
Z10042A Norton
Amplifier. The Z10042A is a surface mount version of the Z10040B Norton
Amplifier, with improved noise figure, improved low frequency response and a
smaller printed circuit board footprint.
|
 |
|
|
|
Z10042AV Norton
Amplifier. The Z10042AV is a redesigned version of the Z10042A to extend
low frequency response to 16 KHz (typical measured figure).
|
 |
|
|
|
Z10043A Norton
Amplifier. The Z10043A is a physically smaller Norton amplifier. It uses
commercially available input and output transformers for easier
construction.
|
 |
High Gain Amplifier
|
Z10046A High
Gain Preamplifier. The Z10046A is a +23.5 dB gain, high performance
(OIP2 typically > +90 dBm; OIP3 typically > +42 dBm) with coverage from 50
KHz to 50 MHz.

Active Antenna
|
|
Z1501 Active Antenna
The Z1501 is a
high performance, compact broadband E-field probe active antenna.
The current Z1501 is the "F" model, Z1501F.
The Z1501 covers the frequency range 20 KHz - 30 MHz (frequency response
extends above 100 MHz with reduced performance) and provides reception similar
to an antenna many times larger.
The Z1501 is provided only as an assembled and tested unit.
The Z1501 is normally used with a DC power coupler such as the Z1203B. |
 |
|
|
|
|
Z1203B Power Coupler.
The Z1203B power coupler performs the same function as the Z1203A—providing
DC power to an active antenna or other remove device—but includes a
rectifier, filter and voltage regulator. The Z1203B is powered by an
external "wall wart" type transformer, so that it functions independently of
other power supplies. The output voltage is adjustable from 9 volts to
24 volts with a maximum supply current of 400 mA.

Z10130A FET Buffer Amplifier
for Dr. Dallas Lankford Antennas
The Z10130A is an FET-based high impedance buffer
amplifier based upon Dr. Lankford's design and intended for use with his
antennas of the active flag and active loop design.

Accessories
|
Z10050A "parts only
kit" contains the electronic parts needed to build a 3dB hybrid coupler.
There is no printed circuit board (one is not needed) and the builder must
supply an enclosure and three connectors.The
photograph shows a Z10050A built from the parts kit.
|
 |
Z10080A bypass relay
kit. The Z10080A can be used with the Z10040B Norton amplifier or
similar device to bypass the amplifier when power is removed. (As a safety
measure to reduce the risk of damage to the amplifier, Clifton Laboratories
amplifiers disconnect the input and switch it to ground through a low value
resistor when power is removed.)
