Unformatted text preview: to the load Power available from the source GT (dB)= PL (dBm) – Pavs (dBm) = 21.67 (dB) Alternatively, GT (dB) = GT(1) (dB) + G(2) (dB) = 8.86 + 12.81 = 21.67 (dB) (e) The available gain of the cascaded 2-port, GA Power available from the second 2 - port Power available from the source Power available from the first 2 - port Power available from the second 2 - port = ⋅ Power available from the source Power available from the first 2 - port GA = = G A(1) ⋅ G A( 2 ) ∴ GA (dB) = GA(1) (dB) + GA(2) (dB) = 10.79 + 12.68 = 23.47 (dB) (f) The operating gain of the cascaded 2-port, G G= Power delivered to the load Power delivered to the first 2 - port ⇒ G (dB) = PL (dBm) − Pin(1) (dBm) = 25.91 dB Alternatively, G (dB) = G1 (dB) + G2 (dB) = 13.1 + 12.81 = 25.91 dB (g) Since 1− | S11 |2 − | S 22 |2 + | D |2 K= = 1.072 > 1 2 | S12 S 21 | and | D | = | S11 S 22 − S12 S 21 | < 1 it is possible to provide a simultaneous conjugate match at the input with Γms and output with Γml , respectively, where B1 ± B12 − 4 | C1 |2 Γms = 2C1 Γml = 2 B2 ± B2 − 4 | C2 |2 2C2 B1 = 1+ | S11 |2 − | S22 |2 − | D |2 * C1 = S11 − DS22 B2 = 1+ |...
