MAX2605–MAX2609 Evaluation Kits

2

_______________________________________________________________________________________

Quick Start

The MAX2605–MAX2609 evaluation kits are fully

assembled and factory tested. Follow the instructions in

evaluation.

Test Equipment Required

• Low-noise power supplies (these are recommended

for oscillator noise measurement). Noise or ripple will

frequency-modulate the oscillator and cause spectral

spreading. Batteries can be used in place of power

supplies, if necessary.

– Use a DC power supply capable of supplying

+2.7V to +5.5V. Alternatively, use two or three 1.5V

batteries.

– Use a DC power supply capable of supplying

+0.4V to +2.4V, continuously variable, for TUNE.

Alternatively, use two 1.5V batteries with a resistive

voltage divider or potentiometer.

• An RF spectrum analyzer that covers the operating

frequency range of the MAX2605–MAX2609

• A 50

Ω coaxial cable with SMA connectors

• An ammeter (optional)

Connections and Setup

GND terminals (through an ammeter, if desired) on

the EV kit.

2) Turn on the DC supply. If used, the ammeter reading
