Abstract:	This paper will descni a small, lightweight and affordable hand-held GPS navigation receiver. The receiver has a internal antenna, measures 6.30 x 2.85 x 1.60 inches, comfortably fiis in the palm on a hand, weights less than 1 pound and runs between 5 to 10 hours with 4 “AA” batteries. Driven by high performance and low cost, a state-of- the-art hand-held GPS Navigation receiver design pushes the technology envelope in both small size packaging and fabrication. Design considerations in these areas will be discussed. Concerning packaging, new packaging of fine pitch TSOP components and small 402 chips are used to minimizes parasitii effects with an overall improvement in performance. High board denstty is also enhanced with higher board dielectric constants and lower toss tangent for excellent performance. Thus, the design and fabrication of a state-of-the-art GPS receiver can bs realized in high volume production ulitizing cost effective surface mount technology. The cost performance window using thin-film ceramic substrates and microwave integrated circuits has been “broken”.
