RF Switches: UPG2409TB-A Application Field and Working Principle

RF switches, also known as switch matrices and switch networks, are active or passive components used to control RF signals by providing a connection between inputs and outputs. RF switches are widely used in communication, satellite and telecommunications applications, and are available in a range of topologies, such as single-pole double-throw (SPDT), double-pole double-throw (DPDT), and single-pole multiple throw (SPMT). Among the RF switches available, the UPG2409TB-A is a high-performance, ultra low-power, ultra-wideband SPDT switch with a temperature range of -40°C to 125°C. This switch is commonly used in mobile applications and it operates on frequency bands from 400 MHz to 6 GHz.

Applications

The UPG2409TB-A switch can be used in a variety of applications, such as antennas, duplex radio, transmit/receive (T/R) modules, mobile phones, millimeter wave (mmWave) 5G system, internet-of-things (IoT) devices, base stations, remote radio heads (RRHs), point-to-point (PtP) links, satellite communication systems, and phased array designs. It can also be used in aerospace and defense systems or automobiles.Specifically, in mobile phone applications, the switch is used to move the antenna calibration signals between primary and diversity RF paths. The switch is also used to route RF signals between transmit and receive paths in radio or T/R modules. In addition, the triple-throw (T/P/T) form of the UPG2409TB-A (UPG2409T3A) is used to route the multiplexer (MUX) input signals or alternatively for the antenna isolation in the antenna system.

Working Principle and Key Features

The UPG2409TB-A switch is a passive device, meaning that it does not require any power supply or external bias circuits. The switch relies on the PIN diode arrays in each channel to create low Insertion Loss (IL) and high isolation (Internal Isolation, External Isolation) between ports.The UPG2409TB-A is designed with a high power handling capability to meet the requirements of mobile and other high-power applications. It supports a maximum input power of 55 dBm. The switch also provides industry leading low-loss performance from 400 MHz to 6 GHz. It has a typical return loss (S11) of -45 dB and insertion loss (S12) of 0.6 dB.The switch has a wide operating temperature range and can be used in extreme temperature environments. The UPG2409TB-A also has high reliability, with a field life of > 50,000 cycles, and is compliant with European Union’s (EE) RoHS and REACH regulations.Overall, the UPG2409TB-A is an ideal solution for high-performance RF applications due to its compact design, high power handling capabilities, low insertion loss, and high isolation over a wide frequency range.
