1 50Ω 3700 MHz (fixed) The Big Deal Low phase noise and spurious Fixed frequency without external programming Integrated microcontroller Robust design and construction Case size 2.75" x 1.96" x 0.62" CASE STYLE: KG1446 Product Overview The is a, designed to operate at 3700 MHz, suitable for a variety of military & commercial applications. The is packaged in a shielded metal case (size of 2.75" x 1.96" x 0.62") to shield against unwanted signals and noise. Key Features Feature Low phase noise and spurious: Phase noise: -91 dbc/hz 10 khz offset Comparison spurious: -85 dbc typ. Reference spurious: -85 dbc typ. No programming or reference required Good frequency stability Advantages Low phase noise and spurious improve system EVM (Error Vector Magnitude). The Internal microcontroller and reference allow the ZSN- 3700AC+ to begin generating RF signal as soon as DC power is applied with no other controls required. Frequency stability of 3.7 khz typ provides a stable signal over time with no need for adjustments or reprogramming. Page 1 of 7

2 Connectorized 50Ω 3700 MHz (fixed) Features Fixed frequency without external programming Integrated microcontroller High reliability over temperature changes Robust design and construction Low operating voltage (VCC =+5V) Case size 2.75" x 1.96" x 0.62" Applications Military & Avionics CASE STYLE: KG1446 Connectors SMA Female Model +RoHS Compliant The +Suffix identifies RoHS Compliance.
