A 5 GHz 0.18 µm CMOS Mixer for 802.11a WLAN Receiver Applications

This article presents a 5.7 GHz CMOS single-balanced mixer for an IEEE 802.11a WLAN receiver application. The RF input frequency of the mixer is 5.725 to 5.825 GHz, the LO frequency is 5.445 to 5.545 GHz and the IF is 280 MHz. The mixer is fabricated w...
Due to the fast growing demand for broadband wireless communications, the operating frequency band is moving toward the 5 GHz U-NII band. The advantage of combining baseband and the RF front-end on a single chip for cost savings is strongly desired for highly integrated systems-on-chip (SoC) applications. Due to...

Printed Circuit Realization of a Capacitive-loaded Interdigital Bandpass Filter

A tapped capacitive-loaded interdigital bandpass filter has been realized using multicoupled suspended substrate stripline (MCSSS). Composite effects of multiple quasi-TEM modes and coupling between non-adjacent strips have been accounted for. Two filt...
The demand for small, compact, low cost, high performance filters, diplexers and multiplexers using MIC technologies has increased along with advances in microwave systems. Capacitive-loaded interdigital filters are compact in size, have sharp roll factor, excellent broad stopband performance and are easy to fabricate. A filter with tapped-line is...
