Broadband silicon RFIC amplifiers

30 June 2004 Analogue, Mixed Signal, LSI

Agilent Technologies has expanded its ABA series of silicon RFIC amplifiers suitable for a wide range of IF and buffer stages in DBS low-noise block downconverters (LNBs), cable television distribution and cable modems, GSM/CDMA radio cards, microwave links, fibre-optic systems, and many other communications applications.

Two of the new RFIC amplifiers feature single-supply 3 V operation for higher efficiency and lower power dissipation. The company claims that the SOT-363 packaged ABA-31563, ABA-32563 and ABA-54563 offer greater power output capability from amplifier stages at higher frequencies, increasing linearity, and higher drive levels for power amplifiers in high-performance wireless applications.

The amplifiers now offer competitive noise figures with linear output power levels ranging from +2,2 dBm to +16,1 dBm, and third-order output intercept points from +13,1 dBm to +27,8 dBm. Like the previous ABA series RFICs, the new amplifiers feature unconditional stability combined with input and output VSWRs of less than 1,5, and internal input and output 50 Ω matching, making them easy to integrate.

The new RFICs have the following features:

* The 3 V ABA-31563 operates over DC to 3,5 GHz. At 2 GHz, it offers a small-signal gain of 21,5 dB, linear output power (P1dB) of +2,2 dBm, +13,1 dBm output third-order intercept point (OIP3) and 3,8 dB noise figure.

* The 3 V ABA-32563 operates over DC to 2,5 GHz. At 2 GHz, it features 19 dB gain, +8,4 dBm P1dB, +19,5 dBm OIP3 and 3,5 dB NF.

* The 5 V ABA-54563 operates over DC to 3 GHz. At 2 GHz, it features 23,1 dB gain, +16,1 dBm P1dB, +27,8 dBm OIP3 and 4,4 dB NF.
