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.

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.

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.

Z1501 Active Antenna
The Z1501 is a
high performance, compact broadband E-field probe active antenna.
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 available as a kit (critical components pre-installed and
adjusted) or as an assembled and tested unit.
The Z1501 is normally used with a DC power coupler such as the Z1203A. |

Z1203A DC Power
Coupler. The Z1203A DC power coupler provides a method of duplexing RF
signal and DC power over a single coaxial cable.
Possible applications include remote mounted Z10040B
Norton amplifier and the Z1501D Active Antenna.
The Z1203A has low coupling loss over the range 20 KHz
- 30 MHz and is usable 10 KHz - 100 MHz. It includes remote power control
and "Active Pull Down" which work together to provide fast switching of
remote devices produced by Clifton Laboratories into "safe" mode to prevent
damage from nearby high power transmitters.

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.)
|
 |
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.
|
 |
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.
