Appeal 2007-1362
Application 09/972,107
signal path from amplifier 202 to pass through at least two switches, 204 and
206, in order to reach any of the antennae 208A-208C (Specification 5:27-
29). Appellants provide a switching network which does not require that the
amplifier signal pass through two switches to reach each antenna
(Specification 6:11-22). As shown in Figure 3, by appropriate selection of
switch 304, a signal at link 310 from amplifier 302 may be provided to link
312A, which routes the signal to antenna 208A, or to link 316B, which
further routes the signal through switch 318 either to antenna 208B or to
antenna 208C (id.).
Independent claims 1, 11, and 18 are representative and read as
follows:
1. An [sic] transponder system, comprising:
an amplifier network having a plurality of amplifiers;
an antenna network, comprising a plurality of antennae;
a single rail output switching network, including a first output
switching network switch, selectably coupling one of the amplifiers to
one of the plurality of antennae at a first output switching network
switch first switch state and to a second output switching network
switch in a first output switch network switch second switch state; and
wherein the second output switching network switch is
selectably coupled to a second one of the plurality of antennae in a
second output switching network switch first switch state and to a
third one of the plurality of antennae in a second output switching
network switch second switch state.
