Embodiment 2

[0158] 14 shows a schematic plan view of a high-frequency power module of another embodiment (Embodiment 2) of the present invention when a part of the sealing body is removed.

[0159] In Embodiment 1, the circuit part includes three low noise amplifiers (LNA) 24 as the designated circuit part 11 . In Embodiment 2, in addition to the above-described circuit components, in the VCO, the RFVCO 44 that handles high frequencies is used as a designated circuit component. Therefore, all the ground electrode terminals 9 of the RFVCO 44 are connected to the lead (ground lead) 7 through the wire 10, while the ground electrode terminal 9 is not connected to the tab 4 through the wire.

[0160] For the line from the electrode terminal 9 of the semiconductor chip 3 to the lead 7 through the wire 10, ground wires are provided on both sides of the two signal wires of the RFVCO 44, thus providing electromagnetic shielding for the signal wires.

[0161] Therefore, the ground potential of the...

Embodiment 3

[0163] 15 shows a schematic plan view of a high-frequency power module of another embodiment (Embodiment 3) of the present invention when a part of the sealing body is removed.

[0164] Embodiment 3 relates to an example in which the RFVCO 44 is provided as an external mounting member so that the semiconductor chip 3 is not formed in a monolithic circuit. In this dual-band communication method, various circuit components such as low noise amplifiers, mixers, VCOs, synthesizers, IQ modulators / demodulators, frequency dividers, DC-AC modulators, etc. are formed as monolithic circuits .

[0165] The two mixers in the receiving system are respectively controlled by a frequency divider, and the frequency divider is a frequency conversion circuit for converting a high frequency signal output from the RFVCO 44, which is an externally mounted component, into a low frequency signal.

[0166] Therefore, in Embodiment 3, as shown in FIG. 15 , the RFVCO 44 is provided outside the semicond...

Embodiment 4

[0169] 16 and 17 relate to a high-frequency power module according to another embodiment (Embodiment 4) of the present invention, wherein FIG. 16 shows a schematic plan view of the high-frequency power module when a part of the sealing body is removed, and FIG. 17 shows the high-frequency power module. Schematic cutaway.

[0170] Embodiment 4 is characterized in that the tab 4 serving as a common ground terminal and the lead wire 7 taking the ground potential are electrically connected to each other using a wire 10b, and the lead wire 7 also serves as a ground external electrode terminal. In the semiconductor device 1 of Embodiment 4, since the back surface of the tab 4 is exposed from the back surface (mounting surface) of the sealing body 2, the tab 4 can be used as a ground external electrode terminal while being connected to the tab by the wire 10b The lead 7 of 4 also serves as a grounded external electrode terminal.

[0171] FIG. 18 is a modification of Embodiment 4. FI...
