We've just added two new Mini-modules to our Mini-module family
--
BL2 Wideband 1:1 & 4:1 (Switchable) 250W Balun
Our highly-efficient BL2 balun can handle up to 250 watts and can handles 1:1
and 4:1 ratios via an on board switch. It is very small (just 1.5 x 3") and
lightweight, making it an excellent choice for both home and field use. It uses
a special winding technique to reduce losses and extend the useful range,
resulting in an SWR of less than 1.2:1 from 500 kHz to 55 MHz (200-ohm load). It
includes rugged screw terminals for the balanced output as well as ground, and
can be used in a variety of matching applications.
Price: $34.95
Specifications:
Power Rating: 250 watts maximum.Bandwidth: Input VSWR less than 1.2 when
connected to a 200 resistive load, 500 kHz to 55 MHz.

CP1 Directional Coupler
The CP1 is a dual directional coupler that provides high directivity, can be
internally or externally terminated and can be constructed with a coupling loss
of either 20 dB or 30 dB. It can be used to sample a transmitter's forward power
and reflected power output. As an example the forward power port can be
connected to an oscilloscope for display of the transmit envelope. It is an
ideal companion to the 2T-Gen 2 Tone test generator. For more advanced
applications is can be used with a spectrum analyzer and tracking generator to
sweep the return loss (SWR) of an antenna or other device in real time over a
frequency range.
Price: $39.00
Specifications:
Frequency Range: 1 MHz to 30 MHz
Coupling Loss: 20 dB or 30 dB (29.8) +/- 0.25 dB
Directivity: 30 dB
Power Rating: 30 dB coupler, 250 W; 20 dB coupler, 25 W
