DETAILED ACTION
Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention.
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claims 1, 8-9, 17, and 19 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by US 2021/0391829 to Srinidhi Embar et al. (“Embar”) (cited in an IDS).
With respect to claim 1, Embar discloses in Fig. 1 a radio frequency power amplifier, for connecting to a radio frequency output device (e.g., 102 is coupled to an RF device outputting to 102) and a signal transmitting device (e.g., 106), comprising:
a first amplifying branch (e.g., 130), comprising a first transistor (e.g., 136) and a first output circuit (e.g., 140), a gate of the first transistor (e.g., 136) being connected to the radio frequency output device (e.g., 102 is coupled to an RF device outputting to 102), a drain of the first transistor (e.g., 136) being connected to a first end of the first output circuit (e.g., 140), and a second end of the first output circuit (e.g., 140) being connected to the signal transmitting device (e.g., 106); and
a second amplifying branch (e.g., 150), comprising a second transistor (e.g., 156) and a second output circuit (e.g., 160), a gate of the second transistor (e.g., 156) being connected to the radio frequency output device (e.g., 102 is coupled to an RF device outputting to 102), a drain of the second transistor (e.g., 156) being connected to a first end of the second output circuit (e.g., 160), and a second end of the second output circuit (e.g., 160) being connected to the signal transmitting device (e.g., 106);
wherein the first output circuit (e.g., 140) comprises a line with an electrical length of 50 degrees to 90 degrees formed based on capacitors and inductors (e.g., inductors and capacitors of 140 form a conductor line for a signal from 136 to pass through and has a length between 60 to 150 degrees, wherein the 90 degree in the foregoing range is also within the claimed range of 50-90 degrees as per Para. 19), and the second output circuit (e.g., 160) comprises a line with an electrical length of 120 to 180 degrees formed based on capacitors and inductors (e.g., inductors and capacitors of 160 form a conductor line for a signal from 156 to pass through and has a length between 91 to 179 degrees, wherein the 179 degree in the foregoing range is also within the claimed range of 120-180 degrees as per Para. 19).
With respect to claim 8, a power distributor (e.g., 110) has an input terminal connected to the radio frequency output device (e.g., 102 is coupled to an RF device outputting to 102), a first output terminal (e.g., 135) connected to the gate of the first transistor (e.g., 136), and a second output terminal (e.g., 155) connected to the gate of the second transistor (e.g., 156).
With respect to claim 9, a first gate bias circuit (e.g., 128) has a first end connected to the gate of the first transistor (e.g., 136) and a second end connected to a fourth power supply (e.g., 137).
With respect to claim 17, a second gate bias circuit (e.g., 129) has a first end connected to the gate of the second transistor (e.g., 156) and a second end connected to a fifth power supply (e.g., 139).
With respect to claim 19, a wireless signal transmitting system, comprises: a radio frequency output device (e.g., the cellular/wireless infrastructure in which the Fig. 1 circuit is used as per Para. 2), a signal transmitting device (e.g., 106), and the radio frequency power amplifier according to claim 1 (e.g., 130 and 150 as discussed for claim 1), the radio frequency power amplifier (e.g., 130 and 150 as discussed for claim 1) being connected to the radio frequency output device (e.g., 102 is coupled to an RF device outputting to 102) and the signal transmitting device (e.g., 106) respectively.
Allowable Subject Matter
Claims 2-7, 10-16, and 18 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
