Reconfigurable 1:3 power divider using coupled lines

Abstract

A reconfigurable 1:3 power divider is presented using quarter-wave long coupled lines and switches. The proposed power divider allows dual operating mode, or a 1:3 power divider and 1:0 power transmission mode, by turning the switches on and off. To make a high power-division ratio of three realisable and improve the bandwidth, a microstrip-slot structure is adopted on a thick substrate with high dielectric constant. The measurement of the proposed power divider shows good return and insertion loss performance in both modes.

Five Ports Power Divider Designs With Controllable Power Division and Switching Capabilities

“…To control the power division ratio, a reconfigurable mechanism should be introduced to the power divider design. Such reconfigurability in power dividers can be implemented using MEMS [2,3], PIN diodes [4][5][6], RF switches [7], and varactor diodes [8]. In [2], a 5-states power divider, which can be reconfigured using MEMS switches, has been proposed.…”

“…The divider has a dual-band performance and can be switched to achieve the three ratios of 1:1, 2:1, and 3:2 in both bands. Several dual-state 2-way power dividers which can be reconfigured using PIN diodes have been proposed [4][5][6]. In these dividers, the power division for the first state is always 1:0, whereas the achieved ratio in the second state is 1:1 in [4], 1:3 in [5], and 1:5 in [6].…”

In these dividers, the power division for the first state is always 1:0, whereas the achieved ratio in the second state is 1:1 in [4], 1:3 in [5], and 1:5 in [6]. It is designed to operate in two states; the first with a specific division ratio and the second with the power routed from one output port to another.…”

“…More specifically, the power divider must provide a state of operation where the input power is routed to a specific output port. Reconfigurable power dividers designed for such a scheme are demonstrated in [4][5][6]12].…”

Microstrip quad mode reconfigurable power divider

“…With the rapid development of mobile communication devices, with various wireless applications integrated on the same device; there is a dire need for systems with reconfigurable capability [1][2][3][4][5][6][7][8][9][10], such as reconfigurable antennas. In literature several successful attempts were made to design reconfigurable power dividers or couplers to utilize in dual state amplifiers, polarization and frequency agile antennas.…”
