The high frequency characteristics feature. Extremely low loss and a high degree of matching.
2.Power Uniform Distribution and 90 Phase Difference Type
HD-0053M3-IH HD-0195M3-DH HD-0195M3-DH-1 HD-0900M3-CH-1
This is a one input, two output (or two input, one output) power uniform distribution type having a 90 phase difference between the two outputs (or two inputs).
3.Miniature and Lightweight
HD-0620M3-EH HD-1700M3-FH HD-3900M3-BH HD-0313M3-FH
Corrosion-resistant aluminum is used for the cover and the Hirose Electric original pattern design, which uses a stripline triplate method, enables the couplers to be extremely small and lightweight.

sMounting Method
The three types of mounting methods illustrated in the diagrams below will mount the card coupler for use under optimum conditions. The fastening screws in the diagrams are M2 screws tightened to 1.5 kg * cm. When the tip of the micro stripline is of Teflon type material ( r = 2.6), C chamfering of C1 is performed at t1.6, and of C0.5 at t1.2. The side view diagrams of Figure 1 are illustrated in Figures 2, 3, and 4 below. Gap S between the card coupler and the microstrip board surface should be used to agree with the following conditions. Below 500 MHz ........S0.5 mm 500 to 2300 MHz ......S0.25 mm Above 2300 MHz......S0.15 mm

qWhen the Ground Board is Constructed of 0.4 mm Stainless and 0.8 mm Aluminum
(When the Thickness of the Microstrip Board is 1.6 or 1.2 mm)
For t1.6 boards, use with the stainless case of the card coupler facing upward. For t1.2 boards, use with the aluminum case of the card coupler facing upward. Mount and fix the card coupler with fastening screws as illustrated in Figure 2. Next, solder the tabs and micro stripline, then use.
(When the Thickness of the Microstrip Board is Greater than 1.6 mm)
Insert a metal plate or a conductive spacer between the coupler and ground, then mount as illustrated in Figure 3 so that the surface of the tabs and the position of the microstrip board are equal. Fix the card coupler with fastening screws as illustrated in Figure 3. Next, solder the tabs and micro stripline, then use.
(When the Thickness of the Microstrip Board is Less than 1.2 mm)
Cut the ground at the position of the coupler and attach so that the surface of the tabs is in contact with the micro stripline. Fix the card coupler with fastening screws as illustrated in Figure 4. Next, solder the tabs and micro stripline, then use.

For VE Items (in which Aluminum Is Used Above and Below the Ground Board and the Eyelets Protrude Beyond the Cover)
The height of the cover will be a value 0.1 mm less than one half of the overall thickness.
For Directional Card Couplers (HD-0900M (10 dB) and HD-0900M (20 dB),etc.)
The height of the cover will be a value 0.35 mm less than one half of the overall thickness.
(When Spacing H of the Micro Stripline Board and the Tabs is 0 H 0.3 mm)
Fix the card coupler with fastening screws as illustrated in Figure 2. Next, solder the tabs and micro stripline, then use.
(When Spacing H of the Micro Stripline Board and the Tabs is H < 0)
Insert a metal plate or a conductive spacer between the coupler and ground, then mount as illustrated in Figure 3 so that the surface of the tabs and the position of the microstrip board are equal. Fix the card coupler with fastening screws as illustrated in Figure 3. Next, solder the tabs and micro stripline, then use.
(When Spacing H of the Micro Stripline Board and the Tabs is H > 0.3 mm)
Cut the ground at the position of the coupler and attach so that the surface of the tabs is in contact with the micro stripline. Fix the card coupler with fastening screws as illustrated in Figure 4. Next, solder the tabs and micro stripline, then use.
At the time of soldering, solder with a space of 1 mm from the edge of the micro stripline as illustrated in Figure 5.
