Abstract

In this paper, the dual band low noise amplifier is designed in 0.18-μm CMOS technology. By combining the proposed switchable load inductor for gain controlling and the conventional inductive source degeneration topology, narrow band gain and good impedance matching are achieved at 2.3/3.3-GHz frequency bands. The new mathematical analysis of low noise amplifier design is derived to define the component parameters of the proposed circuits. The proposed low noise amplifier exhibits gain of 17.18 dB and 15.5 dB, and noise figure of 2.67 dB and 2.52 dB at the two frequency bands, respectively.

Abstract

This paper presents a fully integrated concurrent 15/30-GHz dual-band low-noise amplifier (LNA). The proposed concurrent LNA IC is designed and simulated in 130-nm BiCMOS technology. The new passive LC notch filter is proposed to realize high gain and low noise figure over dual-band frequency, simultaneously. The simulated BiCMOS LNA IC has exhibited peak gains of 30.1/23.7 dB at 15/30-GHz, respectively, with 20-mW power consumption from 1-V supply. The concurrent dual-band LNA achieves noise figure of 2.2/2.9-dB and IIP3 of -18.2/-8.8 dBm at the respective passbands. Therefore, the proposed dual band concurrent LNA IC is applicable to front-end RF receivers for Ku-Band and Ka-Band systems.

Abstract

Ada banyak teknologi mobile broadband wireless access (m-BWA) yang saat ini digunakan, agar bisa mencakup seluruh teknologi m-BWA yang ada dalam sebuah perangkat maka diperlukan teknologi multiband . Salah satu komponen penting yang mendukung perkembangan teknologi m-BWA adalah bandpass filter (BPF), yang berfungsi untuk memilah-milah dan mengisolasi band yang spesifik dari interferensi pada transceiver radio frequency (RF). Pada penelitian ini akan dirancang quadband BPF yang beroperasi pada frekuensi tengah 950 MHz dan 1,85 GHz untuk aplikasi GSM, 2,35 GHz untuk aplikasi WiMAX, dan 2,65 GHz untuk aplikasi LTE secara simultan. Rangkaian quadband BPF dibangun dan dikembangkan dari konsep dualband BPF dengan menambahkan sejumlah cross coupling pada inductive coupling BPF tersebut untuk menghasilkan zero pada frekuensi tertentu yang diharapkan menggunakan komponen lumped. BPF yang dirancang memiliki spesifikasi, input return loss (S11) < -10 dB, insertion loss (S21) > -3 dB, dan voltage standing wave ratio (VSWR) antara 1 – 2, dan group delay kurang dari 10 ns. Perancangan dilakukan menggunakan perangkat lunak Advance Design System (ADS) dan kemudian difabrikasi berbasis printed circuit board (PCB). Hasil simulasi BPF menunjukkan kinerja quadband BPF memenuhi kriteria perancangan sedangkan hasil fabrikasi mengalami pergeseran.
