MAX19994A Highest linearity, l

maxim expands its family of pin-compatible downconverting sige mixers with a new device targeting the 1500mhz market.
dual sige mixer has superior linearity, noise performance, and integration.
sunnyvale, ca—june 3, 2010—maxim integrated products (nasdaq: mxim) introduces the max19994a, a fully integrated, 1200mhz to 2000mhz, dual downconverting mixer with an on-chip lo switch, buffer, and splitter. designed using maxim's proprietary monolithic sige bicmos process, this device delivers an unparalleled combination of linearity, noise performance, and component integration. a single ic provides two independent downconversion channels, each with a +25dbm (typ) iip3, 8.4db (typ) conversion gain, and 9.8db (typ) noise figure. additionally, the max19994a offers an industry-best 2lo-2rf spurious rejection of 68dbc for an rf level of -10dbm, and 63dbc for a level of -5dbm. this mixer is designed specifically for 2.5/3g/4g wireless-infrastructure applications in which high linearity and a low noise figure are critical for enhanced receiver sensitivity and blocker immunity. the max19994a supports high-side lo injection architectures for 1200mhz to 1700mhz wcdma/lte base stations; it can also be configured for 1700mhz to 2000mhz gsm/edge, wcdma/lte, td-scdma, and cdma2000® low-side injection architectures.
as a complete sige downconverter, the max19994a integrates two state-of-the-art mixer cores; four amplifiers; three baluns; an lo switch, buffer, and splitter; and dozens of discrete components. the device's 8.4db conversion gain enables the elimination of a complete if amplifier stage within the receiver lineup. the max19994a's outstanding 2lo-2rf and 2rf-2lo performance can also ease the filtering requirements of close-in harmonics, thus leading to simpler and more cost-effective filter designs. through this combination of integration and performance, the device reduces mixer solution size by a factor of 2x and the discrete part count by 45%.
the max19994a is packaged in a compact, 6mm x 6mm, 36-pin tqfn that is pin compatible with the max9985/max9995/max19985a/max19993*/max19995/max19995a series of 700mhz to 2200mhz dual mixers, and pin similar to the max19997a/max19999 series of 1850mhz to 4000mhz dual mixers. this complete family of downconverters is ideal for applications in which a common pcb layout is used for multiple frequency bands. prices start at $9.96 (1000-up, fob usa).
