RF relays are a type of radio frequency (RF) switch that allow for control of input or output signals across an established range. The ARXP1112 is the most recent example of such a relay, and this article will provide a technical overview of its features and capabilities.

The ARXP1112 is a rugged, passively cooled, switch-mode RF relay. It is designed for a wide range of applications, from low-power consumer electronics to high-power telecommunication rigs. It features a wide range of frequency coverage – from 100 MHz up to 6000 MHz – and high linearity performance with a maximum insertion loss of 0.3 dB. It also comes with a -70 dBc input IP3 and dynamic range of over 75 dB. The ARXP1112 also offers a wide dynamic range and low leakage current characteristics.

The ARXP1112 is a switchable RF switch that can route signals from one antenna to another, and vice versa. It can be used in applications such as multi-antenna base station systems, LTE/4G and 5G wireless systems, and satellite link systems. The switch is designed to operate in extremely harsh environments and has an operating temperature range of -40°C to +90°C. It is also highly reliable, with a mean-time-between-failure (MTBF) of more than 100,000 hours.

The ARXP1112 is designed to operate in a constant frequency mode, using a voltage controlled oscillator (VCO). In this mode, the frequency and power stays constant. The switch speed of the ARXP1112 is extremely fast, with a switching time of only 20 nanoseconds. It also has a low insertion loss, allowing for wideband applications with high performance. The ARXP1112 also features a wide control voltage range of 0.9 V – 5 V, so it can be easily integrated into existing systems.

The working principle of the ARXP1112 is based on a diode switch concept. The basic idea is to use a power diode to create a bridge between two circuits. When the power diode is not connected to the circuits, the RF signal does not transmit across the bridge. When the power diode is connected, the signal is sent from one circuit to the other. In this way, the ARXP1112 can act as a switch to control the transfer of signals between two circuits.

Overall, the ARXP1112 is ideal for applications requiring a robust, high linearity, switch-mode RF relay. It offers a highly reliable solution with a wide frequency range and low insertion loss. The switch speed is also extremely fast, making it suitable for various applications requiring fast switching. It can be easily integrated into existing systems due to its wide control voltage range.
