The QMA connector shares the same internal construction and performance as the SMA series. Yet, the SMA connectors offer an easier, faster, and safer operation because of the innovative coupling mechanism, helping customers save significant time during production. The main difference lies in the interface: QMA connectors feature a 360\u00ba rotating snap-on locking characteristic instead of a threaded coupling, which enables it quick to install with low RF leakage and is tool-less. QMA connectors are commonly used in cellular base station hardware, SCADA radios, and a range of wireless test equipment, where durability, strength, and quick-disconnection features are required. SMA connectors can be rotated 360 degrees after they are mated, which improves the flexibility of installations.<\/p>\n<h3>FEATURES AND BENEFITS<\/h3>\n<ul>\n<li>Snap-on interface for quick and easy installation<\/li>\n<li>High power handling capability<\/li>\n<li>Rotatable 360\u00b0 after connection for flexibility with installation<\/li>\n<\/ul>\n<h3>APPLICATIONS<\/h3>\n<ul>\n<li>Antennas<\/li>\n<li>Base Stations<\/li>\n<li>GPS<\/li>\n<\/ul>\n<h3><strong>QMA CONNECTOR SPECIFICATIONS<\/strong><\/h3>\n<table style=\"height: 373px; width: 100%;\" width=\"100%\">\n<tbody>\n<tr style=\"height: 22px;\">\n<td style=\"height: 22px; text-align: center;\" colspan=\"2\" width=\"362\"><strong>QMA Connectors Specifications &#8211; 50Ohm<\/strong><\/td>\n<\/tr>\n<tr style=\"height: 22px;\">\n<td style=\"height: 22px;\">Impedance<\/td>\n<td style=\"height: 22px;\">50 Ohm<\/td>\n<\/tr>\n<tr style=\"height: 22px;\">\n<td style=\"height: 22px;\">Frequency Range<\/td>\n<td style=\"height: 22px;\">DC &#8211; 18 GHz<\/td>\n<\/tr>\n<tr style=\"height: 44px;\">\n<td style=\"height: 44px;\">Voltage Rating<\/td>\n<td style=\"height: 44px;\">335 Volts RMS Continuous<\/td>\n<\/tr>\n<tr style=\"height: 44px;\">\n<td style=\"height: 44px;\">Dielectric Withstanding Voltage<\/td>\n<td style=\"height: 44px;\">1000 VRMS Max<\/td>\n<\/tr>\n<tr style=\"height: 22px;\">\n<td style=\"height: 22px;\">VSWR\u00a0 (Return Loss)<\/td>\n<td style=\"height: 22px;\"><\/td>\n<\/tr>\n<tr style=\"height: 22px;\">\n<td style=\"height: 22px;\">DC &#8211; 3 GHz<\/td>\n<td style=\"height: 22px;\">1.052 (-32 dB) Max<\/td>\n<\/tr>\n<tr style=\"height: 22px;\">\n<td style=\"height: 22px;\">3 &#8211; 6 GHz<\/td>\n<td style=\"height: 22px;\">1.12 (-32 dB) Max<\/td>\n<\/tr>\n<tr style=\"height: 22px;\">\n<td style=\"height: 22px;\">Insulation Resistance<\/td>\n<td style=\"height: 22px;\">5000 M\u2126 Min<\/td>\n<\/tr>\n<tr style=\"height: 22px;\">\n<td style=\"height: 22px;\">Center Contact Resistance<\/td>\n<td style=\"height: 22px;\">2.5 m\u2126 Max<\/td>\n<\/tr>\n<tr style=\"height: 21px;\">\n<td style=\"height: 21px;\">Outer Contact Resistance<\/td>\n<td style=\"height: 21px;\">3.0 m\u2126 Max<\/td>\n<\/tr>\n<tr style=\"height: 44px;\">\n<td style=\"height: 44px;\">RF Leakage<\/td>\n<td style=\"height: 44px;\">-120 dB Max (DC\u00a0&#8211;\u00a03 GHz)<\/td>\n<\/tr>\n<tr style=\"height: 22px;\">\n<td style=\"height: 22px;\">Insertion Loss<\/td>\n<td style=\"height: 22px;\">.06 \u221a(f(GHz)) dB Max<\/td>\n<\/tr>\n<tr style=\"height: 22px;\">\n<td style=\"height: 22px;\">Power Handling<\/td>\n<td style=\"height: 22px;\">75 W @ 10 GHz @ 25\u00baC<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Note: These characteristics are typical and may not apply to all connectors.<\/p>","protected":false},"excerpt":{"rendered":"<p>QMA CONNECTORS (QMA Adapters).<\/p>\n<ul>\n<li><strong>Product Series:<\/strong> QMA<\/li>\n<\/ul>\n<p>Contact JAW-DROPPER with your required quantity and application for product selection and a quotation.<\/p>","protected":false},"featured_media":27357,"template":"","meta":{"om_disable_all_campaigns":false},"product_brand":[],"product_cat":[317,31,312],"product_tag":[116,123,124,126,320,321],"class_list":["post-28679","product","type-product","status-publish","has-post-thumbnail","product_cat-qma-adapters","product_cat-rf-coaxial-connectors","product_cat-qma-connectors","product_tag-coaxial-cable-connector","product_tag-coax-connectors","product_tag-rf-connectors","product_tag-coax-connector","product_tag-qma-female-connector","product_tag-qma-jack-connector","pa_product-series-qma","description-off","first","instock","shipping-taxable","product-type-simple"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.6 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>QMA CONNECTORS | JAW-DROPPER<\/title>\n<meta name=\"description\" content=\"QMA CONNECTORS (QMA Adapters).
