  1. BGA 2003 (Silicon MMIC amplifier): In general, the function of a preamp is to amplifya low-level signal to line-level. • FEATURES: • Low current. • Very high power gain. • Low noise figure. • Integrated temperature compensated biasing. • Control pin for adjustment bias current. • Supply and RF output pin combined. Preamplifiers: • APPLICATIONS: • Wideband applications, e.g. analog and digital cellular Telephones, cordless telephones (PHS, DECT, etc.). • Low noise amplifiers. • Satellite television tuners (SATV). • High frequency oscillators.

  2. DESCRIPTION: Silicon MMIC amplifier consisting of an NPN double poly silicon transistor with integrated biasing for low voltage applications in a plastic, 4-pin SOT343R package.

  3. Indoor antenna: • Omni directional antenna is used as indoor antenna. • It's antenna that radiates equally in all directions. • It can be used to link multiple directional antennas in outdoor point-to-multipoint communication systems including cellular phone connections and TV broadcasts. • The only three dimensional Omni directional antenna is the unity gain isotropic antenna. • Practical antennas approach Omni directionality by providing uniform radiation or response only in one reference plane, usually the horizontal one parallel to the Earth's surface. Omni antenna Data sheet (100709): Typical mounting: This small embedded antenna provides the most reliable, easy-to- use and adjustment free antenna technology for handling during assembly and implementation by developers.

  4. Features: • Small and lightweight. • No tuning components. Electrical: • Frequency range: 880-960MHZ; 1710-1990 MHZ. • Peak gain: +1dBi; +1dBi. • VSWR less than 2.5:1; less than 2.5:1. • Polarization linear. • Azimuth beam width Omni directional • Power handling 10 watt cw. • Feed point impedance 50 ohms unbalanced. Mechanical: • Size: 37.59 x 11.94 x 2.77 mm. • Weight less than 2.5 g. • Mounting: surface mounted technology.
