The MRF7S21080HSR3 from NXP Semiconductors is an N-channel enhancement-mode lateral MOSFET (LDMOS) RF power transistor designed for CDMA base station applications from 2110 to 2170 MHz. If you're working on cellular infrastructure amplifiers that need 22 W of linear average power with 18 dB of gain at 28 V, this part is a dependable choice.

This device was originally released by Freescale Semiconductor and now sits within NXP's RF power portfolio. It is suitable for CDMA and multicarrier amplifier applications, and can be used in Class AB and Class C for TD-SCDMA and PCN-PCS/cellular radio. It comes in the earless NI-780S package (Case 465A-06) and is supplied on tape and reel.

 

Key Features of the MRF7S21080HSR3

MRF7S21080HSR3 Component Sense

Proven single-carrier W-CDMA performance

At VDD = 28 V, IDQ = 800 mA and 2167.5 MHz, the MRF7S21080HSR3 typically delivers 22 W average output power with 18 dB power gain and 32% drain efficiency. ACPR is typically −38 dBc at 5 MHz offset, measured in a 3.84 MHz channel bandwidth.

80 W peak capability and rugged construction

Output power at the 1 dB compression point is approximately 80 W CW. The device is capable of handling a 10:1 VSWR at 32 Vdc, 2140 MHz and 80 W CW, giving headroom against load mismatch in the field.

Internally matched for faster design-in

The transistor is internally matched on both input and output, and is characterised with series equivalent large-signal impedance parameters. That simplifies matching network design and reduces tuning time on new or replacement amplifier boards.

Built for linearised and Class C architectures

The MRF7S21080HSR3 is designed for digital predistortion (DPD) error correction systems. A wider negative gate-source voltage range (−6.0 V to +10 V) supports improved Class C operation.

Earless NI-780S package with strong thermal performance

The NI-780S is the earless counterpart to the NI-780 package used by the MRF7S21080HR3. Junction-to-case thermal resistance is 0.65 °C/W at 22 W CW, with a maximum operating junction temperature of 225 °C. The R3 suffix denotes 250 units on 56 mm tape, 13-inch reel.

100% PAR tested, ESD protected and RoHS compliant

Every device is 100% PAR tested for guaranteed output power capability and includes integrated ESD protection (Human Body Model Class 1C minimum). The part is RoHS compliant.

 

Applications of the MRF7S21080HSR3
