This transmission line structure provides for movement of the edge-line center conductor between two fixed, continuous ground planes. The main advantage of this innovation is that the moving contacts can be easily activated, yet maintain high-isolation and low-insertion loss. Unterminated latching The Agilent N1810UL is a single-pole double-throw switch available in the frequency range from dc to 26.5GHz. In precision measurements and monitoring applications where insertion loss repeatability is crucial, these switches operate in excess of 5 million cycles with better than .03 dB of insertion loss repeatability at 25 C. N1810TL Terminated latching The Agilent N1810TL is a single-pole double-throw switch available in the frequency range from dc to 26.5 GHz. The unused port is terminated 50 ohms, making it ideal for applications where port matching is required. N1811TL Terminated latching The N1811TL is a terminated bypass switch available in the frequency range from dc to 26.5 GHz. The switch's internal load can terminate the device under test when in the bypass mode (up to 1 watt). Because of its compact design, it is ideal for drop-in, drop-out applications. The RF contact configuration is designed for controlled wiping action. Since the outer conductor is not part of the switching function, repeatability and life are improved. The switching action occurs typically within 15 milliseconds, after which permanent magnets latch the contacts to retain the new switch position. Operation All switches are "break before make": the switched ports are not connected to each other. This helps to prevent possible damage to sensitive circuits and enhances test simplicity. N1812UL Unterminated latching The N1812UL is a versatile, unterminated 5-port switch available in the frequency range from dc to 26.5 GHz. In transfer switch applications, the fifth port can be terminated externally with a highpower termination. It can also be utilized for signal path reversal or as a calibration port. Driving There are two positions for the N181x family of switches. Standard switching is accomplished by applying the supply voltage to pin 5 (+V) and grounding either pin 4 (DA) or pin 3 (DB) to actuate the mechanism to the desired state. See page 3, Pin out diagram.. When option 403 is added, the drive current is automatically disconnected after the switch is fully latched (15ms). Without option 403, the switches MUST be actuated using a pulse drive--the switches are not designed to withstand continuous current. In this case, the pulse duration must be at least 15ms to ensure that the switch will fully latch. Option 401 drives the switch with TTL/5V CMOS compatible logic. Option 402 provides electronic indication of switch state. The circuitry consists of two independant commons, which can be connected to outputs corresponding to either position A or B. Because the commons are electrically isolated from each other as well as the drive circuit, this option allows two position signals to be obtained.
