Abstract

A radio frequency integrated circuit (RFIC) includes a die and a package. The die includes a radio frequency (RF) input/output (I/O) section, an RF to baseband conversion section, and a baseband processing section. The package includes a ball grid array and an antenna. The antenna is located on one edge of the package and the solder balls of the ball grid array proximal to the antenna are used to couple the RF I/O section of the die to the antenna.

Claims (13)

1. A radio frequency integrated circuit (RFIC) comprises:

a die containing a radio frequency (RF) input/output (I/O) section, an RF to baseband conversion section, and a baseband processing section; and

a package having a ball grid array and an antenna, wherein the antenna is located on one edge of the package, and wherein solder balls of the ball grid array proximal to the antenna are used to couple the RF I/O section of the die to the antenna.

2. The RFIC of claim 1 , wherein the package further comprises at least one trace coupling the solder balls to the antenna, wherein the at least one trace has an inductance that has minimal affect on conveying RF signals between the antenna and the RF I/O section.

3. The RFIC of claim 1 further comprises:

the die is in a first position within the package to minimize adverse affects of parasitic components of coupling between pins of the package and the RF I/O section when the package is a first package; and

the die is in a second position within the package based on the values of the parasitic components when the package is a second package such that parasitic components of coupling between pins of the second package and the RF I/O section substantially match the parasitic components of the coupling between the pins of the first package and the RF I/O section.

4. The RFIC of claim 3 , wherein the first position comprises:

an offset from a center of the first package.

5. The RFIC of claim 3 , wherein the first position comprises:

an edge of the first package.

6. The RFIC of claim 3 , wherein the coupling between the pins of the second package and the RF I/O and the coupling between the pins of the first package and the RF I/O section comprise:

an inductor having an inductance such that adverse affects of the parasitic components of the coupling are minimized.
