This article presents the design, simulation, implementation, and experimental results of a highly efficient, concurrent dual‐band, gallium nitride (GaN), class‐AB power amplifier (PA) at two frequencies: 1.84 and 3.5 GHz. It proposes a novel dual‐band bandpass filter (DBBPF) with quad‐section stepped‐impedance resonators (SIRs) capable of rejecting the annoying frequencies of the second and third harmonics in the dual‐band. The proposed DBBPF was applied in the design of a dual‐band PA using a packaged 10 W GaN transistor. The PA prototype maintained a peak power‐added efficiency (PAE) of 75.3% at the 1.84 GHz frequency and 64.5% at the 3.5 GHz frequency. For a continuous wave output power of 40.9 dBm, the measured gain was 13 dB in the two frequency bands. Linearized modulated measurements, concurrently using 10 MHz quadrature amplitude modulation (16 QAM) signals and worldwide interoperability for microwave access (WiMAX) signals, showed an average PAE of 48.5% and 39.8% and an adjacent channel leakage ratio of −46 and −45 dBc with an average output power of 37.8 and 36.8 dBm at the two frequency bands, respectively. This PA is used for wireless systems. It is especially useful in standard simultaneous global system for mobile (GSM) and WiMAX wireless systems.

“…This analysis shows that Mode I and f z depend on the parameters of radial stub, while Mode II depends on the parameters of open ended transmission line. The radial stub can be seen as a series combination of inductor ( L r ) and capacitor ( C r ) . The resonant frequency of series LC circuit can be calculated as:

f_{z} = \frac{1}{2 π \sqrt{L_{r} C_{r}}}

A novel, ultra‐compact switchable microstrip band‐pass filter–low‐pass filter (BPF–LPF) showing wide stop band and good attenuation characteristics is proposed in this paper. Both BPF and LPF operation utilizes a common geometrical filter section, and individual filter operation is realized by means of the switches operated in “ON” or “OFF” mode. The proposed filter is designed for the dual mode BPF for wireless local area network (5.15–5.35 GHz) application with all four switches in OFF condition and for the LPF at 3 GHz cut‐off frequency with all switches in ON condition. The insertion loss (S21) in the stop band region is below −20 dB extending up to 12 GHz for both the filters. The proposed reconfigurable filter is ultra‐compact having the circuit size of only 5.952 mm × 8 mm = 47.616 mm2. The simulation result is validated experimentally. © 2016 Wiley Periodicals, Inc.

A novel, compact planar switchable filter having good inband and wide out-of-band characteristic with three switching modes [low-pass filter (LPF), band-stop filter (BSF) and band-pass filter (BPF)] is presented. Reconfigurability in this aspect is never reported in literature. The reconfigurability is achieved by using a minimum of five switches. A very good agreement is shown between the simulated and measured results. The overall circuit size of the proposed switchable filter is only 14 mm 3 16.72 mm.
