| Datasheet: SKY13323-378LF - SPDT Switch 1 x 1 mm |
The SKY13323-378LF is a pHEMT GaAs FET I/C switch. The switch may be used in transmit/receive applications by connecting the RF common port (INPUT, pin 5) to either the OUTPUT1 or OUTPUT2 port (pin 1 or 3, respectively) using a low loss path (i.e., a positive voltage applied to either VCTL1 or VCTL2 pins). The switch is “reflective short” on the isolated port.

| White Paper: Guidelines For Choosing RF And Microwave Products: Lumped Element (LC) Filters |
As one of the most fundamental filter types, LC filters are also some of the most useful, since they are extremely versatile in the responses they can achieve, the types (such as low-pass, high-pass, etc.) they can accommodate, and their potential performance. Like all filters however, the best choice for a specific application results from trade-offs that can only be determined if the designer has considerable experience in filter design.

| Datasheet: High-Power Ceramic Diplexers (Surface-Mount) |
In many cases, identification friend or foe (IFF) systems require diplexers to combine transmit and receive channels onto a single antenna. K&L Microwave’s 9DLX0-1030-1090/X8 is used on the interrogator, transmitting at 1030 MHz. The 9DLX0-1090-1030/X8 is for use in the transponder. Both parts are rated to handle 800 watts of peak power and can be used in military airborne and ground applications. |

| White Paper: Computational Magic And The EMC Engineer |
In decades past, the EMC engineer had three basic methods for evaluating EM phenomenon: Maxwell’s Equations, circuit models, and fieldwork. The development of electromagnetic computational methods now provides us with another tool. In its current state of development, however, computational tools will not completely replace any of the methods above. Computer modeling of EM phenomenon in three dimensions requires a host of assumptions that make computational modeling a tricky business. To do it well, the engineer should not only have a working knowledge of Maxwell’s Equations, but should be
familiar with the equally complex field of numerical analysis as well. By Dr. Glen Dash, Ampyx LLC |
