“…Because a regular circulator can obtain around 20-25 dB of isolation [3], it's not suitable to use it in the prototype of the Security Purpose Pulse Doppler Radar which requires more than 40 dB of isolation. If the high isolation isn't achieved, the high power transmitted signal can damage the receiver.…”

This paper describes the design, analysis and measured performance of PIN diode Single-Pole Double-Throw (SPDT) Switch and its feeding circuit. The SPDT switch is done for the prototype implementation of The Security Purpose Pulse Doppler Radar which is intended to be used for security applications. Shunt-Shunt Switch topology which includes two cascaded quarter-wavelength sections that each one is terminated by a shunt diode is chosen in order to achieve high isolation between transmit and receive port. The switch feeding circuit is designed and manufactured successfully for pulse generation.Also, 12V to 6V bias converter circuit designed for the switch ground. Since the prototype gets continuous power from Tx port, it produces pulses successfully when it operates in Tx mode. As a result, the circuit can be used as a switch and a pulse generator in the Security Purpose Pulse Doppler Radar system for the 1.2-1.25 GHz frequency range.

“…Filter-integrated switch (FIS) as depicted in Figure 1 is another integrated/multifunction device. From the year 2006 onwards, numerous studies have reported filter-integrated double pole double throw (DPDT) switch [5], single pole single throw (SPST) switch [6][7][8], and SPDT switch [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. In order to produce FISs and integrate BPF with SPDT switch in one device, several techniques have been used, such as dielectric resonators (DRs) [15], LC resonators [11], substrate integrated suspended line (SISL) [30], and common shorted stepped-impedance resonator (CSSIR) [25].…”

In this paper, an absorptive filter-integrated switch (FIS) using switchable T-shape resonators is presented. The FIS was made up of two absorptive T-shape resonators and integrated with single pole double throw (SPDT) switch. A simple mathematical analysis of isolation and insertion loss of filter-integrated SPDT switch is discussed. PIN diodes were used as the switching elements for the SPDT switch and to reconfigure between the band-stop and bandpass responses. The proposed absorptive FIS design could be used for internet of things (IoT) applications such as Zigbee and Bluetooth at an operation frequency of 2.45 GHz. As a result, the proposed FIS exhibited low magnitude of insertion loss and high isolation. Therefore, the key advantages of the proposed FIS design are low insertion loss, high isolation, and good return loss at both ON-and OFF-state ports.

“…Resonant method is demonstrated in [3] by tuning with a parallel inductance to compensate the elements capacitive effects. They achieve as high isolation as 40 dB at the cost of worse insertion loss which is more than 1 dB.…”

Abstract-Two SPDT switches that have low insertion loss with impedance-transformation networks are presented. The proposed SPDT switches are comprised of two shunt PIN s and two quarterwavelength microstrip lines together with impedance transformation networks, which canceled the capacitance effect at off-state and the inductance effect at on-state simultaneously. The simulated insertion loss performance is less than 0.3 dB and the fabricated ones exhibit on-state low insertion loss of 0.5 dB within the range of 4.6-4.8 GHz.
