Reflective Microwave Switches
Reflective Microwave Switches are essential components of RF/microwave circuits. Their VSWR and insertion loss are crucial for creating consistent and reliable circuits. This article describes the characteristics of these switches, and offers recommendations for choosing the right one for your application. We have also provided links to a variety of sources for RF/microwave switches. Read on to learn more about each one. Listed below are some of their benefits and features. You should contact with us for microwave Test and Tag service.
The F9016 is an example of a reflective switch. It operates from 100 MHz to 40 GHz, providing insertion loss less than 5 dB. Its switching time is less than 250 nsec, and it supports up to 200 mW of power. These switches require a voltage range of -15 to 5 V, and they consume less than 60 mA of current. This makes them ideal for ultra-wide band applications.
Performance
This paper discusses the performance of reflective and non-reflective microwave switches. The switches’ characteristics are evaluated in terms of impedance matching and insertion loss. Reflective switches don’t provide a good termination. Non-reflective switches are designed with terminations. The PIN diode and shunt terminations used in absorptive microwave switches have the least penalty for insertion loss. The MACOM MASW-011102 is a low-power SPDT non-reflective switch. It supports a wide frequency range, from DC to 30 GHz, and a high-performance switch, incorporating a patented low gate-lag GaAs process. It is also lead-free, featuring a 14-Lead PQFN plastic package. The switch is fabricated by a robust process and features full-surface passiva.
The performance of reflective microwave switches depends on the design and material. The newest high-performance SPDT switches from Integrated Device Technology (IDT) feature low insertion loss, excellent isolation and power handling, and are available in a small 2-mm package. The switches are specified for 50 or 75-O systems and are highly versatile and suitable for a wide range of applications. They are used in BTS wireless communication equipment, DOCSIS 3.1 CATV equipment, consumer products, and more.
Impedance matching
When looking at reflective microwave switches, the first thing you should keep in mind is the difference between VSWR and the total impedance. VSWR is a ratio between the amplitudes of the reflected and incident signals. It can be expressed as one or infinity depending on the reflection coefficients. The ideal match is a 1:1 ratio. VSWR is usually expressed as a number.
The problem with this approach is that it is a naive solution to impedance matching. The best solution is to directly transition the impedances. That way, the device will accept the worst-case reflection, but you will not be able to transmit the full power of the signal. For example, when you step from 50O to 75O, you will receive about 4% of the input power reflected, while the remaining 96% is transmitted. This reflected power can cause real problems in many systems.
Application
The application of reflective microwave switches is a growing market, particularly in wireless communication systems. This type of switch is characterized by its low in-band leakage, a characteristic desirable in high-frequency applications. It is also easy to insert into HTS transmission lines. In addition, it can be driven via an external control line. It has been tested and found to have an insertion loss of less than 1 dB, a 30 dB isolation, and response times of microseconds, which are more than adequate for many microwave/millimeter-wave applications.
The F9016 from Kratos is a reflective SPST switch that operates from 100 MHz to 40 GHz. Its switching time is 250 nsec. It is designed to handle up to 200 mW of power. It requires a -15 to 5 V supply voltage and only consumes 60 mA of current. Its small size makes it an excellent choice for ultra-wide band applications. You can find a variety of these switches, and it is easy to find the right one for your application.
