Pin Switch Protects Lna From Overloads, Chin-Leong Lim

Chin-Leong Lim

The objective of this paper is to describe how a Microwave Monolithic Integrated Circuit (MMIC) can be paired with an external PIN diode bypass switch in the implementation of a Low Noise Amplifier (LNA) with overload protection feature for mobile TV receiver applications. In the preliminary phase of the design, competing schemes for reducing LNA gain were reviewed and their respective cost-performance trade-offs were benchmarked against the customer’s set of requirements. Based on the selected design, a “proof of concept” prototype was then assembled and tested. The key components of this switch by-passable LNA were sourced from in-house product portfolio, …

Chin-Leong Lim

Objective: This paper describes how a Microwave Monolithic Integrated Circuit (MMIC) can be paired with an external PIN diode bypass switch in the implementation of a Low Noise Amplifier (LNA) with overload protection feature for mobile TV receiver applications.

Method: In the preliminary phase of the design, competing schemes for reducing LNA gain were reviewed and their respective cost-performance trade-offs were benchmarked against the customer’s set of requirements. Based on the selected design, a “proof of concept” prototype was then assembled and tested.

Material: The key components of this switch by-passable LNA were sourced from in-house product portfolio, consisting of …
