Description
The 1P603 Pico Xinger is a low profile, miniature 3dB hybrid coupler in an easy to use surface mount package designed for W-LAN and MMDS applications. The 1P603 is designed for balanced amplifiers, variable phase shifters and attenuators, LNAs, signal distribution and is an ideal solution for the ever-increasing demands of the wireless industry for smaller printed circuit boards and high performance. Parts have been subjected to rigorous qualification testing and units are 100% tested. They are manufactured using materials with x and y thermal expansion coefficients compatible with common substrates.

AMPLITUDE BALANCE 3dB hybrids are a type of backward wave coupler. In the design of these couplers, the even mode impedance was chosen to `critically couple' or slightly `over couple' at mid band to maximize performance and bandwidth. The amplitude balance specification is defined as the difference (in dB) of the signals at the COUPLED port output and the DC port output, when compared to the average output level. PHASE BALANCE In theory, output ports of a backward wave hybrid coupler remain in perfect phase quadrature independent of frequency. In practice, factors associated with the manufacturing processes slightly degrade performance. The specification is typical two to three degrees maximum although in practice, phase balance is statistically better than specified (<1o).
VSWR & ISOLATION Similar to phase balance, the VSWR and isolation of a coupler are theoretically perfect; where the input and output ports are perfectly matched and no power is coupled to the isolated port. In practice, factors associated with the design and manufacturing processes limit VSWR and isolation. The significant limitations are associated with limitations of building perfect 50 transitions at the input and output ports of the device. INSERTION LOSS Coupler insertion loss is defined as the difference of the input power from the sum of the output power. In practice, loss is typically 0.20 dB. Specification limits are somewhat higher due to imperfect test conditions;

PIN CONFIGURATION
electrical and mechanical stability having X and Y thermal coefficient of expansion (CTE) of 17 ppm/oC When a surface mount hybrid coupler is mounted to a printed circuit board, the primary concerns are; insuring the RF pads of the device are in contact with the circuit trace of the PCB and insuring the ground plane of neither the component nor the PCB is in contact with the RF signal. As long as the geometry of the unit fits onto the layout of the circuit trace on the PCB, and the conditions of the previous paragraph are followed, the coupler's performance is ensured. An example of how the PCB footprint could look is shown below. In specific designs, the 50 lines need to be adjusted to the unique dielectric coefficients and thicknesses as well as varying pick and place equipment tolerances. SUGGESTED FOOTPRINT
To ensure proper electrical and thermal performance there must be a ground plane with 100% solder conection underneath the part
All of the standard surface mount 3dB hybrid couplers have pin orientations that are symmetrical. When a port is designated as the input, automatically the two output and isolated ports are defined. For example, if the input port for a device was selected to be Pin 1, Pin 2 is automatically the isolated port, Pin 4 is the 0 degree reference output port, and Pin 3 is the output port which "lags" behind the reference output port by 90 degrees. Similarly, if Pin 3 was to be selected as the input port, the adjacent port on the long side (Pin 4) is the isolated port, the adjacent port on the short side (Pin 2) is the 0 degree output port, and the opposite port (Pin 1) is the 90 degree output port. Below is a table of all possible orientations. MOUNTING In order for Xinger surface mount couplers to work optimally, there must be 50 transmission lines leading to and from all of the RF ports. Also, there must be a very good ground plane under the part to ensure proper electrical performance. If either of these two conditions are not satisfied, insertion loss, coupling, VSWR and isolation may not meet published specifications. Overall ground is improved if a dense population of plated through holes connect the top and bottom ground layers of the PCB. This minimizes ground inductance and improves ground continuity. All of the Xinger hybrid and directional couplers are constructed from ceramic filled PTFE composites which possess excellent
