automatic gain control - smt 21 hmc993lp5e v 0 0.0 911 rf automatic gain controller (rf-agc), 700 - 3000 mhz application information introduction the hmc993lp5e is a complete high performance automatic gain control (agc) solution, housing a variable gain amplifer (vga) core and a control core in a single package. its unique vva technology provides constant oip3 over the entire control voltage range. the hmc993lp5e greatly simplifes the design of gain control loops by increasing the integration level and reducing the number of required circuit elements. the vga core of the hmc993lp5e is composed of two identical voltage variable attenuators followed by two gain block amplifers which operate from 0.7 to 3.0 ghz. the hmc993lp5es control core features a high accuracy log detector. as shown in the functional block diagram, the hmc993lp5e combines all of these cores in a highly compact 5 x 5 mm plastic package, and offers an easy-to-use, temperature stable agc solution. the hmc993lp5s vga core has a fexible structure where a single attenuator (22.2 db at 1900 mhz) or two attenu - ators (33.6 db at 1900 mhz) can be used depending upon the dynamic range requirement. inputs and outputs of the hmc993lp5es attenuators and frst amplifer (attin1, attout1, attin2, attout2, ampin1, ampout1) are broadband matched to 50 ohm single-ended and require only external dc blocking capacitors over the entire fre - quency band of operation. the input of the hmc993lp5es log detector (rfdetin) is also broadband matched to 50 ohm single-ended and does not require any matching components. input and output of the hmc993lp5es second amplifer (ampin2, ampout2) need power matching components for key application frequencies. refer to applica - tion circuits for example application frequencies. the hmc993lp5e requires a single 5v supply with adequate power supply decoupling as recommended in the appli - cation schematics. figure 1a: the hmc993lp5es vga confguration with 1 attenuator, 1900 mhz tune. for price, delivery and to place orders: hittite microwave corporation, 2 elizabeth drive, chelmsford, ma 01824 phone: 978-250-3343 fax: 978-250-3373 order on-line at www.hittite.com application support: phone: 978-250-3343 or apps@hittite.com
