The MA4SPS402 is a high power, wideband, single-pole double-throw (SPDT) switch from Avago Technologies. It is a part of their Hittite Microwave High Power Switch Series. This device is a discrete component intended for use in applications such as antenna switching, linearized control of power amplifiers, and automatic gain control (AGC) functions.

The MA4SPS402 is capable of handling a maximum power of up to 3.1 W (CW) and an operating frequency range of 9 kHz to 4 GHz. It is rated for on-state insertion losses of 4 dB at 900 MHz, 5.5 dB at 2.5 GHz, and 7 dB at 4 GHz. Off-state isolation is 20 dB at 900 MHz and 16 dB at 2.5 and 4 GHz.

This model is a two-pole, two throw (SPDT) switch. It consists of two independently operating ports, each of which can be switched from one state to another using RF signals. The two ports are connected through a common node and can function as either series switches, whereby current flows from one port to the other, or parallel switches, where current is diverted from one port to the other.

The operation of the MA4SPS402 is controlled by two pins: a logic input pin (SDI) and a logic output pin (SDO). The logic input pin controls the switching of the SPDT switch. The logic input pin can be either low or high, depending on the logic input voltage. The logic output pin provides an indication of whether the switch is in an on or off state, allowing the control and monitoring of the switch’s status.

The MA4SPS402 is a good choice for applications that require high power handling and high isolation levels. Its small size and low cost make it ideal for RF applications such as cellular phones, base station and user equipment, instrumentation and test systems, and automotive components. It can also be used in medical equipment and military applications.

The MA4SPS402 is also well suited to applications that require low power consumption, such as low-power operation. Its low power consumption, along with its small size and low cost, makes it highly desirable for applications in the field of wireless communications, where power efficiency and cost are critical factors.

In summary, the MA4SPS402 is a high power, wideband, single-pole double-throw (SPDT) switch from Avago Technologies. It is capable of handling a maximum power of up to 3.1 W (CW) and an operating frequency range of 9 kHz to 4 GHz, and is well suited for a variety of RF applications. Its small size and low cost make it ideal for applications that require low power consumption, such as low-power operation.
